This product is designed to help students prepare for working within 1,000 in third grade. So much work done within 1,000 involves students decomposing larger numbers into smaller ones. Because of this, it is critical for third grade students to be able to efficiently and accurately work with the smaller numbers first. This fluency work is designed to help students become more proficient at adding and subtracting within 100. Students will practice making smaller numbers, adding and subtracting in number frames, comparing numbers using base-10, adding and subtracting on number lines, adding within 100 using money, subtracting within 60 using clock number lines, and adding and subtracting within 100 using a hundreds chart. This would be great for intervention, small groups, whole group teaching, or for your centers/rotations!
