Practice counting within 120 and skip counting by 2s, 5s and 10s within 120 with these first grade math rings. These rings are differentiated to allow for two levels of practice. There are 2 different math rings with two different levels. 1. The first fill in the missing number ring has one blank for students to fill in the missing number in the number sequence. The second, more difficult, ring has 2 blanks for students to fill in. 2. The second set of math rings is for skip counting. Students will determine if the sequence is skip counting by 2s, 5s or 10s and then fill in the missing number. The second, more difficult set is missing 2 numbers in the sequence. You can cut out and laminate the rings for students to write directly on the rings. There is also an optional recording sheet available to record the answers from the rings.
