This is an activity or craftivity that can be used during your subtraction unit. Using the umbrellas and raindrops or snowflakes and clouds your students can create a large scale regrouping versus no regrouping anchor chart. Print the raindrops and snowflakes out and mix them up to give two to each student. They will have to use their subtraction skills to solve the problem and decide which umbrella or cloud to place the item under. This can be used for many things during your unit. Enjoy and please leave feedback.
