Egg box maths

For today’s maths challenge you will need an egg box, a piece of paper, a pen, a pair of scissors and some objects/toy.  If you don’t have an egg box don’t worry you can still do this challenge by drawing a tens frame on a piece of paper.

Step 1:

Cut your egg box to make 10 spaces or draw out your tens frame, just like the ones at school!

On a piece of paper write out the numerals 1-10 and cut them out to make digit cards.

Step 2:

Turn all of the digit cards over so you cannot see the numeral and shuffle them up.

Turn one card over. Can you put that many objects into your egg box or tens frame?

I chose numeral 9 and put 9 stones into my egg box! I counted as I put them in and then I recounted to check I had 9.

 

Step 3:

This step is for Reception children… Something you hear Miss Hughes say a lot!

“PROVE IT!” 

How do you know that is 9? What can you tell me about number 9?

Its 9 1s.

9 is one less than 10 and there is one empty space in my egg box.

9 is 5 add 4 and i know that because the top row is full and then there are 4 more on the bottom row!

9 is the same as 1+1+1+1+1+1+1+1+1

9 is the same as 2 + 2+ 2 +2 + 1.

 

Which numbers will you choose? Don’t forget to prove it!

If you find this challenge easy maybe you could use two egg boxes or two tens frames and explore numbers to 20!
