# Week beginning 15/3/21

This week in maths we are learning to:
1. solve + and - missing number problems

2. understand how to partition numbers into tens and ones.

## Monday 15th March

Today we are looking at + number problems e.g. 5 + ? = 16. To do this we will be using a number line and a part whole mode.

First, find what numbers in the calculation are a whole numbers, and which are one of the parts. We will need to find the other part number to make the whole.

To do this, you need to find and circle to find number in your calculation first and then find and circle the answer to your calculation. You can then count the difference between the 2 numbers to find the missing number! Remember to count forwards as we are adding.

Give it a go using the PowerPoint examples, and then have a go at the worksheets.

## Tuesday 16th March

Yesterday we looked at + missing number problems. Today we are looking at  - number problems e.g. 16 - ? = 9, which we can solve using the same methods as yesterday. Again, we will be using a number line and a part whole mode.

First, find what numbers in the calculation are a whole numbers, and which are one of the parts. We will need to find the other part number to make the whole.

To do this, you need to find and circle to find number in your calculation first and then find and circle the answer to your calculation. You can then count the difference between the 2 numbers to find the missing number! Remember to count backwards as we are subtracting.

Give it a go using the PowerPoint examples, and then have a go at the worksheets.

### Wednesday 17th and Thursday 18th March

Over the next few days we will be looking at how we can partition numbers into tens and ones. When we partition numbers we can use equipment called 'dienes'. The 'sticks; represent tens and the individual cubes represent ones.

Work through the PowerPoint to understand this more. Have you got any toys at home that you can use to partition numbers? You can use sticks as tens, leaves as ones or lego pieces! Then have a go at the worksheets!
