BLM-20 and BLM-21 : The students can use Cuisenaire rods to start to associate number lines with length. They are learning to partition a number line with concrete materials. They will see that when we use a number line we are counting the area or length, not the dashes on the line. In the write about it section they can write a number sentence 2+3=5, or they can say red and green equal the same length as yellow.
There is an open problem at the end where they can choose what rods they use and then show the 'hops' on the number line.
BLM-22 A fun activity where the kids can make a picture with the blocks and then find the area they covered with blocks by counting the squares. It's a bridge between non-standard measurement and standard (these are cm squares). Again they may write the number sentence or describe the picture in words or both. They will count all of the squares, regardless of what colour they are, and come up with a total. If they choose two five cm rods, hopefully they add those together first to make 10 etc.
As usual, I have included learning goal and success criteria.
