**Please note that this will be the final week of maths challenges before the summer break.**

Look at the information here about each person's savings. Read the bubbles.

Decide whether you agree or disagree with each statement.

Can you back up your argument for each statement made?

__Sentence starters:__

I agree because....

I disagree because....

I know that....

I can show that....

**Prove what you are saying by showing a calculation.**

Today, you will find some Sudoku puzzles. Choose your level and have a go! If you dare try 9x9 grid, make sure you use the hints to help you.

Today's challenge is all about taking your rounding skills to the next level - to use rounding to solve problems.

**Remember: You could just pick the next step from yesterday's learning.**

Today's challenge is all about rounding to the nearest 10, 100 and 1000.

Choose your level.

Remember the rhyme:

5 and above, you round up,

4 and below, down you go.

If you are rounding to the nearest 10, the rule applies to the units (ones) column.

If you are rounding to the nearest 100, the rule applies to the tens column.

If you are rounding to the nearest 1000, the rule applies to the hundreds column.

**NB: Full worksheets for rounding have been added below. Thursday's challenge will involve some word problems.**

**However, if you concentrate on rounding to the nearest 10, on Thursday you could challenge yourself to have a go at the next level (which could be rounding to the nearest 100).**

Have a go at these word problems.

Read them carefully.

Think about which operations you may need to use.

Good luck!

Today, is another challenge where you have to use the inverse (opposite) operation to work backwards to fond the starting number. Good luck!

When thinking about this problem, think about the following:

1) How many leaves are on 10 twigs?

2) How many leaves did the Deca tree have before the woodcutter came along?

3) How many leaves did the woodcutter chop off each time?

Good Luck!

Dec translates to 10. Hence the tree is called a 'Deca' tree.

Once you have solved the Deca tree problem, you could invent your own tree such as a five branched 'Penta' tree or an eight branched 'Octa' tree.

You could sketch your tree or create a model of one. Pipe cleaners could work well for this purpose.

The below problems are set so that you can practice your division skills from last week. Good luck!

The below problems are a bit harder as they involve using a three digit number.

Today, for those of you who may be missing our Friday mental maths, attached is two tests. For those of you who want more practice, you can do both or you can choose your level. Most of you can do the year 4 paper - so don't try fooling your parents otherwise.

Today, you will find resources below so that you can have more practice with the written methods for division. Below the images you will find a Powerpoint presentation, which you will need to view as a slide show to appreciate the steps that you need to take. The more you practice, the better you will get. The written method for division catches so many of you out on mental arithmetic tests.

More questions to practice (optional) as I know some of you like to practice lots of written calculations.

Set out the questions as above - using the bus stop method. Below, you will find the extra questions on a PDF format. However, you will also find full worksheets to practice, if you wish.

Today, the challenge is still all about division but moving on from metal calculations to showing your answers using the written method (the bus stop).

Use the following link, which contains a video clip to help you:

https://www.bbc.co.uk/bitesize/articles/zmcpscw

The clip talks about the dividend, the divisor and the quotient. These sound like tricky words. See below for the definitions.

Dividend = the number that is being shared or divided.

Divisor = the number that you are dividing by - so how many groups.

Quotient = the answer.

You can choose which box that you have a go at.

If you want it to be more difficult, then you can choose the last box at the bottom.

Use these examples to practise and then tomorrow there will be another division related challenge.

Today, the maths challenge is all about division, using partitioning (splitting the number into H T and U) and mental calculations. Remember, division is the inverse (opposite) of multiplication so you can use your multiplication skills to help you. We can also describe division as sharing into equal groups. With more complex division calculations, you may have remainders - numbers that do not fit equally into a group and are left over.

Look at the pictures below. These show examples on each picture there are questions for you to try. (PDF version for printing is available below).

Today's challenge is all about problem solving and finding all possibilities. It may take a while to do. Take your time, have patience and think logically. This will test your brain in a totally different way. There are many possibilities and for those who enjoy a challenge, you can make a larger 'V' and include different numbers.

Today's challenge is all about using inverse (opposite) operations. You will need to work backwards through each challenge to find each number.

Today's challenge is all about negative numbers.

Remember:

1) Negative numbers are the numbers below zero.

2) The larger the negative number, the smaller the number actually is and therefore the furthest away from zero.

E.g -10 is smaller than -7

This is because -10 is the furthest from zero.

Use a number line to help you (PDF version below).

We also see negative numbers when representing temperature. Water freezes at zero degrees centigrade. -5 degrees centigrade is colder than 0 degrees centigrade. (Just like 0 degrees centigrade is colder than 2 degrees centigrade.)

Use the number line to help you answer the following questions:

Today is all about times tables. Below you will see an image of calculations. However, the numbers are disguised as different shapes.

**Each shape represents a number from 0 to 12.** Therefore, the value of each shape can not be 13 or above.

**Hint: Look at the first calculation.**

**The numbers multiplied are the same shape (**purple square**) so their value is the same.**

___ x ____ x _____ = _____

**Work methodically: **

So, 1 x 1 x 1 = 1 (1 x 1 = 1 Then,multiply the answer by 1 again - so 1 x 1 = 1)

**Note that the answer is the same as the numbers multiplied. Above the answer is a yellow semi-circle. This will not be the same number as the purple square.**

2 x 2 x 2 = 8

(2 x 2 = 4 4 x 2 = 8)

3 x 3 x 3 =

To work this out, you need to multiply the fist two numbers, then multiply your answer by the last 3 in the multiplication sentence. What is the answer? Does it conform to the rules?

If not, what must the value of the square be?

From this point, you should be able to work out the rest.

Good luck!

Today, for a change, is a game for you to play. To make it more challenging, you may increase the number of counters/objects.

Good luck!

__Maths Challenge 29.05.20__

Today's challenge is all about finding __ all__ the possibilities that could exist. You will have to think logically and be methodical.

There are 8 possibilities to this problem. Can you find them all?

**Read the problem carefully. **

**Remember:**

1)There are 4 containers - so you need four amounts.

2)They have to total 20 litres.

3)You are working with exact amounts (so you don't need to use decimals).

4) All containers hold at least 2litres, but no more than 10 litres.

**Challenge:****If you find all 8 possibilities, you could then use decimal numbers but just stick to 0.5 (half).**

**E.g - using the rules 1,2 and 4**

**One possibility would be:**

**2.5l, 6l, 4.5l and 7l**

**2.5 + 6 + 4.5 + 7 = 20 litres**

Good luck!

Read the questions carefully. Remember the strategies we use in school. You may have to carry out more than one stage to solve the problem. Think about answering the questions in context.

__ Hint:__ You will have to work backwards (using the inverse) to find the number at the start of the problem.

**Maths Challenge: 19.05.20**

Remember to check your calculations using the inverse operation!

**Maths Challenge: 18.05.20**

Look at the problem below. You need to make sure each possibility totals £3.80.

One example answer would be:

7 gel pens (7 x 50p = £3.50) and 1 pencil (30p)

£3.50 + 30p = £3.80

Now you give it a go! Good luck

**Maths Challenge: 14.05.20**

Look at the two statements below (PDF also available). Can you use your reasoning skills to say whether you agree or disagree with Thinking Tom. How can you prove what you think? Show your thinking/working out.

**Maths Challenge: 12.05.20**

Now try with four digits...

**Maths Challenge: 11.05.20**

Use your place value knowledge to work out the maths riddles below. I'll start you off with just 3 digit numbers. Challenge a member of your family; who can get the correct answer first! Remember, always check your answers!

Using the fruit prices from yesterday, answer the remaining four questions.

Remember to use the strategies below. Read the question carefully and consider what the question wants you to find out. How are you going to solve the problems? Is there anything that you learned from yesterday (if you made mistakes) that can help you today?

Good luck! As always, please find printable versions below. The prices of the fruit can be found on the document containing questions 1-4.

Use the information below (the cost of the fruit) to calculate the answers to the money problems.

Remember: Read the question carefully. You may need to make jottings and calculate the answer using a number of steps.

Use __ RUCSAC__ to help you.

**R** - Read the problem.

**U** - Understand the problem.

**C** - Choose the operation(s) you will use.

**S** - Solve the problem.

**A** - Get your answer. Does it answer the question originally asked? **Can you write your answer as a sentence?**

**C** - Check your answer to ensure that it makes sense. You may want to use the **inverse** (opposite operation to check). Use your answer and work backwards to see if you get back to where you started.

Today, something different! You are going to use your addition and subtraction skills to play a game. You could try this with an adult at home or a sibling (brother or sister).

Supporting documents and powerpoint can be found below.

Have ago at these problems. If you finish these and if you finish see the link below for some BBC Bitesize maths challenges. These should definitely make your brain work! Good luck and try your best.

https://www.bbc.co.uk/bitesize/articles/zv8v382

As always, the above problems can be found as a PDF format below (for printing).

Look at the two statements below (PDF also available). Can you use your reasoning skills to say whether you agree or disagree with Thinking Tom. How can you prove what you think? Show your thinking/working out.

__Answers will be added later in the week! See PDF file below...__

__Maths Challenge-23rd April __

Multiplication and division problem solving. Remember to use R U C S A C ( read, understand, choose, solve, answer and check) when working the following problems out. The four pages have been saved onto one PDF document (below).

â€‹â€‹â€‹â€‹â€‹â€‹

Today, there are a range of maths based puzzles for you to complete. Below, you will find printable versions of two wordsearches and three different sudoku puzzles all at different levels (including a 9x9 grid for those who want an extra challenge). With the sudoku puzzles, you can copy the grids out to complete (and the same for the wordsearches if you want). This will also help with your use of a ruler and your measuring skills. I would measure 1cm boxes for each number or letter. You could make the grids larger by measuring 2cm squares.

For the Sudoku, you will find that the answers will be added next week.

__Maths Challenge: 20.04.20__

__Ring a ring of numbers__ **Below are PDF files, including a recording sheet for your solutions!**

Today's challenge is all about Roman numerals. Can you remember all the rules?

Warm up: Write a list of roman numerals 1-20.

**Remember: **

1) If the smaller multiple is written **before** the larger one, you **subtract.**

If the smaller multiple is written** after **the larger multiple, you **add**.

**E.g **

IV = 4 because the one is written before the 5, so 5-1 = 4

VI = 6 because the one is written after the 6, so 5 + 1 = 6

IX = 9 = 10-1

XI = 11 = 10 +1

2) As the numbers become larger, you have to partition the numbers into their columns to work out the answer.

__Remember:__

I = 1

V = 5

X = 10

L = 50

C = 100

D = 500

M = 1000

** Challenge** – Convert the below numbers to Roman numerals

- 93
- 119
- 178
- 299
- 546
- 888
- 994
- 1547
- 2690
- Today’s date – 16/04/2020

**Maths Challenge 15.04.20**

Moving on from yesterday, the challenge is to make one whole using decimals.

Remember: decimals (decimal fractions) split the whole number into equal parts. So after the decimal point, the whole number is firstly split into tenths and then hundredths.

E.g - 0.3 + 0.7 = 1 **This is the same as 3/10 + 7/10 = 10/10 = 1**

E.g - 0.47 + 0.53 = 1 **This is the same as 47/100 + 53/100 = 100/00 = 1**

Then, have a go at the worksheets (a PDF copy can be found below for you to print).

__Maths Challenge 14.04.20__

__ Hint:__ Don't forget your place value columns.

You may want to draw a PV chart.

__Maths Challenge: 09.04.20__

__Maths Challenge: 08.04.20__

__Helpful Hints:__

To work out the numbers for the children in green, try starting with the first row. What do you notice about the green numbers?

Can you make the green numbers from any of the other numbers?

Does the rule you found work for the second row of numbers? And the third?

I will post the answers Friday evening!

The answers as promised....

Today's Easter Tasks are Bake it and Play it! See the link below...

https://whiterosemaths.com/homelearning/easter-fun/

** Maths Challenge- 06.04.20**

Remember, 3 groups of __different__ sizes!! Every possibility needs to total 30 children.

**Hints and tips**

** Maths Challenge 01.04.20**

__Read all of the clues...__

Which clue will help you first?

If the number you are rounding ends in 5 or above, round the number up.

If the numbers you are rounding end in 4 or below, round the number down.

The challenge today is something slightly different. Below, please see the Sudoku puzzles. For the smaller grids (4x4), each row, column and smaller square need to contain the numbers 1-4. For the larger grids (6 x 6), each row, column and smaller square need to contain the numbers 1-6. Each number can only be used once in each orientation and direction. Have a go and Miss Lindop will post the answers at the end of the week.

__Can you solve these word problems?__

Can you answer them in context if necessary?
