Counting by 3s, 4s, and 5s
Can learners recognize the pattern in these number sequences? Here's a hint: it's skip counting by either three, four, or five. There are three examples at the top demonstrating each of these, and scholars complete 15 number sequences to...

Counting Out Loud
These number sequences are quite fun to look at! Beginning counters complete six of them as they say and write in the numbers. They count only by 1s, however some of these move from greatest to least. The highest number here is 20. Once...

Patterns of 2, 5, and 10
Give your young counters practice with skip counting and colors as they shade in number grids by 2s, 5s, and 10s. The three grids reach 50, and the first one is partially completed to give scholars an example. They follow directions by...
Curated OER
Counting by 1s, 10s, and 100s
These sequences are missing numbers and require some skip counting to complete. Scholars finish rows of numbers first counting by 1s, then 10s, and finally 100s. Each has three given numbers to get them started, and they fill in five...

Counting by 2s, part 2
Two, four, six, eight...can your scholars count by twos? They fill in missing numbers in 18 number sequences, all of which require skip counting by twos. Some begin on an even number and others odd, however all of these are whole...
