Believe it or not, one of my 8th graders showed me this trick and it blew my mind!

Some of you may be thinking, this isn't a useful resource because it doesn't help the student understand the concept of multiplying by 9 and that's understandable. However, I've taught 4th and 5th grade special education and little tricks like these are a lifesaver and confidence booster when students encounter multiplication problems.
​I really hope you find this helpful too.

"This pack includes a sweet little activity I did as part of my annual evaluation this year. After learning about 2D and 3D shapes, we build them using toothpicks and marshmallows! Each student was given a plate, toothpicks and marshmallows and allowed to let their creativity flow! This lesson allows students to think critically and covers several common core Geometry standards. I’ve also included some shape building cards that I used as needed with some of my struggling students who needed more support. The student can look at the shape first, then build it."
