# Year 1 Maths 10.2.21

Today in maths we are working on comparing sets of up to 50 objects.

Use this counting back in ones 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 less. 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.

Finally, I would like to do some of your own comparing sets of objects.

You can choose to:

Complete the worksheet.

OR

Do this activity practically by creating 2 sets of objects from around your home, such as cars, beads, pasta, counters and compare them. I would recommend arranging the objects on ten frames or in the same formation as ten frames (2 rows of five). Then you can create 2 more sets of objects and compare them.

Grown ups: Encourage your child to say a full sentence to compare the sets, using the words, more than / less than / fewer than / greater than.

If your child is finding these numbers tricky, please work on numbers within 10 and then numbers within 20. Encourage your child to accurately count out sets of objects and to use appropriate language to compare sets as directed above.

Extension Challenge:

Can you explain to a grown up how you know that one number is more than / less than the other number? Can you talk about the number of tens and ones that you can see in the number?
