This is a pack I use for my students to reinforce the 100's chart.
I use a blank 100's chart to pre-assess whether they can complete the chart, and based on the results, I have them practice a variety of tasks.
Students practice by:
1. Filling in the charts where I have pre-filled in some numbers.
2. They also use the final sheet as 100's chart puzzles. I print them on card stock and cut in a variety of patterns.
3. Finally, when they believe they have acquired the knowledge necessary, they can fill in the blank chart to show they understand.
