This is one of my favorite activities to practice recognizing numbers from 11-20. I give each student their own Random Numbers 11-20 coloring sheet. Then I put the Random Numbers 11-20 flipchart up on my board. As I flip through the pages the students have to shout out the number, then color in a square, only one square that has that number on it. There are multiple squares so that each number can be recognized and named multiple times. They can color the squares with a crayon, marker, bingo dot marker, highlighter, etc. I always have them choose their *favorite* crayon...that's usually a big deal! Hope your class loves it as much as mine!
