I have used Touch Math in my classroom for years! It is a great resource for kids of all ages that struggle with memorizing basic math facts.
The students (especially younger ones) have always struggled with the traditional Touch 9. A couple of years ago, I started to show them the 9 with 3 triangles. They just touch the points of each triangle. It has made a world of a difference. The major problem was there are no resources with the Triangle 9, so I made some myself!
Included in this document:
~9 pages of different colored number lines: Great to keep on students' desks or in math folders
~A set of small posters #1-9: Great for small group or to put on your board
~A set of large posters #1-9: Great to display as a number line above the board for students to use as a quick resource
Let me know if you have any questions.
