I and Mathy my mascot solve number line addition problems (and Mathy jumps on the number line!). Initially we use little jumps that are one unit long, and then we on go to use arrows that are longer and match the numbers to be added.
These are easy single-digit addition problems suitable for kindergarten and early 1st grade.
We also solve two word problems - one is an addition word problem and the other is a missing number problem. Lastly, children get to see simple patterns in addition.
