Week 5 - 11.05.20

Place Value 2 - 10's and 1's (Representing Numbers) 

Please remember to send us any pictures of your maths learning this week smiley

This week we will be recapping our understanding of place value (the value of digits/numbers). We will be focusing on numbers within 50 and exploring how best to represent these numbers. As we will be exploring some large numbers this week, you might find it useful to start by listening to and joining in with the 'Big Numbers Song' that is linked below.

To get us started this week, we are going to begin by using practical resources to represent some small numbers. If we were in school we would use a range of resources to help us to represent numbers such as numicon, counters, dienes and multi-link cubes. However, you will need to be as creative as you can with the resources that you have available to you at home, and to use these to help you to represent the numbers listed below. 

Please see the pictures below for some ideas and further clarification.

Can you represent the following numbers using your practical resources? 

3, 16, 19, 10, 13, 20, 5, 7, 15 and 9 

Challenge - Use your practical representations or a 100 square or number line to help you to think about how you could order these numbers from smallest to largest.

Today we are going to continue to explore representations of numbers, but we are going to focus on using 10s and 1s to help us to do this. This means that before we can represent a number we must look at it closely to see how many 10s it has in it, as well as how many 1s. 


Please watch the video below to see an explanation on how to do this. 

Using 10's and 1's to represent numbers...

Use the number generator that is linked below to choose a number between 1 and 50. Whichever number is randomly selected, you should try to represent it using your 10s and 1s. You can do this practically at first if you would like to, but then see if you can challenge yourself to draw your 10s and 1s, just like Miss Fountain has done in the video.


  1. Always start by counting your 10s and then your 1s
  2. Once you have represented your number, make sure that you double check that it is the correct representation by (carefully) counting it once more. 

Number Generator 1 - 50

Press 'pause' to select a random number. Whichever number appears on your screen once the video has paused is the number that you should represent using your 10s and 1s. Repeat this as many times as you would like.

Challenge - Use this sentence stem to help you to describe/discuss each of the numbers that you have represented: 

"_______________ has _____________ tens and ____________ ones." 

For example - "78 has 7 tens and 8 ones." 


Have a go at practising your 10s and 1s knowledge by using the 'Place Value Basketball' game. How many answers can you get right? Can you challenge yourself to beat your record? Make sure that you count the 10s and 1s carefully so that you don't make any mistakes.

Today we are going to combine the skills that we have been learning this week, with the skills that we practised last week (comparing numbers). To do this, we can use our oracy (talking/discussion) skills, but we can also challenge ourselves to use the symbols < > and = to help us to make these comparisons. Remember, last week we used the video below to help us to do this - the crocodile is ALWAYS hungry so he ALWAYS eats the biggest number! Watch the video to remind yourself how to compare numbers using these symbols...

Number Gators (Greater Than, Less Than Symbols Song)

If you don't feel confident using these symbols, you can use your oracy skills to make comparisons instead. Use these sentence stems to help you to do this: 

"______________ is greater than ___________ because __________." 

"______________ is less than ___________ because _____________." 

"______________ is equal to ___________ because ______________." 


For your activity today, you will need to pick two numbers (from the 100 square above) and write them down on a piece of paper (keep your numbers below 50 and challenge/support your child based on their ability). You should then: 

  1. Represent your numbers by drawing 10s and 1s underneath each number

Challenge - talk about the numbers that you have represented (e.g. "______ has _____ tens and _______ ones, but this number has ________."

  1. Once you have represented each number, look carefully at your representations to help you to decide which number is greater than (>), less than (<) or whether the numbers are equal to (=) one another.

Today we are going to be combining what we have learnt this week with our addition skills that we recapped in Week 1. Your activity today is to answer these addition number sentences below. To do this, you should represent each of the numbers that you are adding together, by using your 10s and 1s. Remember: when we are adding, the answer will always get bigger not smaller! 

Watch the video below to help you to do this.

Try your best to answer the number sentences below and make sure that you are presenting your work just like Percy Peacock to really show off your learning from this week. 

10 + 8 =                      20 + 4 = 

12 + 7 =                      12 + 16 = 

15 + 6 =                      21 + 10 = 

17 + 8 =                      20 + 13 = 

13 + 7 =                      32 + 6 =
