This week we would like you explore number pairs that add together to make 10.
This is an exploratory and investigative task to find out which pairs of numbers make 10 and if you can spot any patterns in the pairs of numbers that make 10. You could:
• Start the investigation by watching the Ten Song from Number Blocks https://www.bbc.co.uk/cbeebies/watch/numberblocks-the-ten-song
• Use 10 objects and split them in different ways, counting each smaller group to find out which two numbers can make 10.
• Make a list of the different ways to make 10. This might be by recording the numbers rather than a full addition calculation, or in pictures. If your child wants to write their “number sentence” (3+7=10) then they are welcome to.
• Draw the pairs of numbers that make 10 as Number Blocks.
• See if you can find this out in a logical order, maybe start with 0 and then work through each number.
• Have a close look and see what you notice about your pairs of numbers that make 10. For example, did you have 6+4 and 4+6, what do you notice about these pairs of numbers to make 10.
• As you become more confident, can you start to remember some of these number pairs without looking or using objects? This might sound tricky, but I bet you already knew 5+5=10 without looking!
If your child finds different ways to make 10 using more than 2 numbers, feel free to explore this as an area of number investigation. However, for recall and application of number bonds to 10, pairs of numbers are what we would focus on in school. (0+10, 1+9, 2+8, 3+7, 4+6, 5+5, 6+4, 7+3, 8+2, 9+1, 10+0)
If your child is confident in their knowledge and understanding of pairs of numbers that make 10, you could explore pairs of numbers that make 20. Be sure to look at the patterns of number pairs to 20 and number pairs to 10. For example, 14+6=20 and 4+6=10….what do you notice?
Have fun with your explorations and we look forward to finding out all about them on Tapestry!
