Yesterday we were learning to count in 10s, lets practise that again now... 10, 20, 30, 40, 50 60, 70, 80 90, 100.
Today we are going to be using our hundred square to add 10 to any number. We are going to be learning a special maths trick to help us with this!
Yesterday when we added 10 to a tens number, the answer was underneath it on the hundred square. That is the same for any number than we add 10 to.
On the hundred square below (or your own if you have one at home), point to number 5. If you add 10, by counting 10 jumps you should end up on the number below, 15, check and see if it works.
Let's try this with another number. Start on 24, if you count the 10 jumps (being careful when you have to move rows), then you should end up on 34. This maths trick will work for any number on the hundred square! As an extra challenge we can write this as a number sentence: 24 + 10 = 34.
Independent Task: Choose any number on the hundred square and add 10 to it. You may want to print out the hundred square below to help you or even make your own. IF you would like an extra challenge you can write it as a number sentence.
