Question Video: Recognizing 10 Less Than a Given Number Using Base 10 Blocks Mathematics • Second Year of Primary School

Video Transcript

We want to show that 10 less than 34 is 24. How many ten rods should we take away to show this?

At the moment, our model shows three tens and four ones, which is 34. We need to show that 10 less than 34 is 24. If we take away one ten rod, which is 10 less, we will have two tens and four ones, which is 24. We needed to take away one ten rod to show that 10 less than 34 is 24.
