Product description
From the author
Let young mathematicians practice skip counting by 9's using an engaging 100 or 120 chart! This interactive worksheet allows students to highlight or circle numbers that are nine numbers apart, such as 9, 18, 27, and so on up to 100 or even 120. Seeing the skip counting sequence visually aids learning and builds number sense. Students can refer back to the chart later when solving multiplication problems. For example, instead of memorizing 9 x 4 = 36, students can skip count by 9's (9, 18, 27, 36) to find the answer. This activity lays a foundation for multiplication by showing that skip counting is repeated addition (ex. 9 x 5 = five groups of 9). Use this versatile resource in small groups, as independent practice, or even homework.

Teaching tips & learning objectives
Learning objectives
Skip count by 9s, marking each number said on a number chart.
Recognize the visual pattern multiples of 9 make on a hundred or 120 chart.
Teaching tips
Have students say each number aloud as they highlight it — the instruction ties the marks to the numbers 'you say' when counting.
Start with the to-100 chart and move to the 120 chart once students can carry the pattern past one hundred.
Ask students what they notice about the highlighted squares' diagonal drift — a springboard into why adding 9 is like adding 10 and taking 1 away.
Skills covered
Skip counting by 9s — students count the 9s sequence aloud and highlight each number on the chart, to 100 or to 120.
Number-chart navigation — locating each next number on a hundred or 120 grid reinforces place-value layout.
