With this summer-themed worksheet, kids practice all about number 3! Kids count circles in the ten frames and shade the correct amount of rings. Kids trace the number three several times and write the number that comes after before and after three. Then, kids count and color the number of balls that represent this number. Finally, kids find the number three on the number line and paint it! This worksheet is great for kindergarten students to practice their number sense skills. It comes in two variations: in color and black&white.
