I was planning with my Kinder team today, and the discussion turned to skip counting by tens off the decade. Traditionally, when skip counting by tens was taught, we asked students to count the multiples of ten–10, 20, 30, etc. Counting by tens off the decade involves counting by tens from a number other than a multiple of ten, for example 7, 17, 27, etc.

The hundred chart is a perfect tool for skip counting by tens because of the arrangement of numbers in rows and columns. As you move down a column on the hundred chart, each number is ten more than the number above it. To help students practice skip counting by tens off the decade make two copies of a hundred chart–one on white card stock and the other on colored card stock. Laminate the charts for durability. Cut the colored hundred chart into strips and place the complete chart and strips in a workstation. Students take turns selecting a strip, placing it on the hundred chart, and reciting the numbers.

    This is a great idea! Thanks for sharing! I am thinking that I may use the hundreds chart and cut strips of colored vellum for my RtI 2nd graders. They can slide it over the board and recite the numbers.

    I encourage teachers to skip count aloud before bringing out 100’s chart. Hearing a pattern and rhythm to the counting helps with the 100′ S chart transition. It worked great it my K classroom for 17 years.

    I encourage teachers to use tools such as the hundred bead rack or 100 dot squares and 10 dot strips to model what skip counting is. If students simply recite a pattern, they’re missing out on the conceptual piece of math.

    Remember concrete first. Do it with 10 sticks and ones cubes first. Adding a ten stick each time. C, R, A
