Towards the end of next week (we are bit behind because of the snow days), we will start working with double digit numbers in comparison with other numbers. We will work on identifying a number on the 100's chart and adding 1 and 10 more and taking away 1 and 10 less.
This concept can be difficult because the 100's chart is quite daunting. Lots of numbers and lots to think about! But we will do lots of practice with the 100's chart and work on making little boxes around numbers to help us understand this concept. We will use terms like jump down (adding 10), jump back (subtracting 10) and moving 1 back/left (1 less) and moving 1 forward/right (1 more) to help. Sounds confusing, I know! But this will help them visualize it, even though they'll have their 100's chart always to help. They have their name tags to use or I have some small ones they can use as well.
They will also learn to compare numbers using the greater than/less than signs (< and >) and the equals (=) sign. I use alligator mouths as a way of thinking about greater than and less than. The alligator is hungry and always wants the bigger number to eat, so the sign (open mouth) will point towards the bigger number. Then this topic will move into ordering the numbers from least to greatest and the other way, greatest to leart
This topic has a lot going on so if we need to slow down and wait till Topic 10 we will. It depends on their pre assessment and what I see during math workshop time.
