In this math learning exercise, students learn skip-counting by 2's, 5's and 10's by learning a memory device poem. The 4 verse poem helps students discover number patterns.

For this skip counting worksheet, students solve 3 problems in which they count by twos, fives or tens. The pattern is continued for three numbers that will be written on large primary lines.

Second graders regroup two-digit numbers and solve advanced subtraction problems with regrouping; students use straw and cup manipulatives to demonstrate how to borrow from the tens place in order to solve the problem.
