Wednesday's maths

Date: 13th May 2020 @ 9:56am

Hello,

 Well you  must have all stopped singing because the Sun is out today!!!!!! I have been out this morning walking in the glorious sunshine and feel ready for a day of work. I hope you are too!

Today and for the rest of the week we are going to focus on subtraction. Today is going to give you an opportunity to recap on previous learning and then use this knowledge to learn something new. So let's recap on what we have been learning so far. 

We have read and solved subtaction problems using concrete objects, crossing amounts out and using a number line.

Challenge 1- Using a number line to subtract amounts

Remember that when we subtract amounts from each other the number gets smaller and we count back on a number line to solve the problem.

Have a look at these problems

Challenge 2

Now have a go at subtracting from 10 using a number line. Can you use your knowledge of number pairs to help you ? Please remeber to write your numbers correctly!

Now time for something new!

Challenge 3- Subtraction using the bar method

We use are knowledge of addition to help us solve subtraction problems.

Let's have a look at the first question!

9-8=  we might say that as 9 take away 8 equals.

We could also say that we know that the total amount is 9. We know that 8 is taken away.

What do I need to add to 8 to make 9 and draw it to help you.

Challenge 4- subtraction from 10 using the bar method  

Have a go at writing the bars to match the subtraction 

1. 10-5=     2. 10-7=     3.10-3=     4.10-4=     5.10-1=      6. 10-2=

Happy learning!
