Year 1 Maths 8.2.21



Today in maths we are focusing on finding one more and one less.


Use the Big Numbers song to get you warmed up and ready to start today. Ask a grown up to stop the song in different places so that you can identify the next number - the number that is one more. Click here and get ready to join in.


Now have a look at this video.

You could click here for the power point slides if you would prefer to go at your own pace.

Remember to share your ideas and answers with a grown up.


Finally, I would like you to complete the first half (questions 1 and 2) of this worksheet. We will complete questions 3 and 4 tomorrow.


Grown ups: I would recommend using tens frames and counters / beads / pasta OR objects from around the house to represent the tens and ones eg pencils and counters / beads. This will help your child to see the number and understand what is happening when we find 1 more and 1 less.

Extension challenge:

Pick any number from 1 to 50 and find 1 more or 1 less than that number.

Can you record a calculation to match your 1 more / 1 less problem? Think about which symbols you will need to include.


For example - What is one less than 32? One less than 32 is 31. 32 - 1 = 31

What is 1 more than 46? One more than 46 is 47. 46 + 1 = 47
