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 Back
Where does the frog stop? Help youngster visualize subtraction with a frog on 10 steps. He starts on the step coordinated with the minuend and hops down based on the subtrahend. By doing this, scholars are counting on backwards and...

Counting Circles II
Fill those extra ten minutes of math time with this fun counting activity. Given a short sequence of numbers, young mathematicians stand in a circle and count one-by-one until the last number is reached, at which point the whole group...

How Many Days Until Summer Vacation?
On the 124th day of school, young mathematicians are asked to find out how many days are left in the 180-day school year. The teacher version to the task offers several ways the problem can be solved, and can be used to guide instruction...

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...
Curated OER
Counting Down
It's time for liftoff for these math rockets and the only way to get them into the sky is through the power of subtraction! Scholars begin with a double-digit number, subtracting numbers in a sequence to reach zero. There are four...

How Many Ways Can You Count?
Youngsters chorally count to 100 by 1s, 2s, 5s, and 10s, and backwards from 20, using chip markers and a hundreds chart. Includes a printable chart and a teacher checklist for assessing mastery.

Understanding 10: Backwards and Forwards
Help your young mathematicians completely master 10 by practicing one-to-one correspondence, number recognition, and recording numbers displayed. They make 10 with groups of two-different colored cubes and color in 10-frames to show how...

Primary Counting Skills
Class members drill and practice counting skills from 1 to 20. They count along with a puppet and when the puppet makes a mistake, they correct it. In pairs, they connect cubes to make a train and count the number used. On the last of...

Mentally Add and Subtract 10 or 100
Don't let the title of this one fool you; scholars skip count only by 10 in this number sequence worksheet. They fill in missing numbers on a number line to complete each sequence, adding or subtracting 10. There are two addition...

Frogs Hopping by 2s
Hop to it! Beginning counters fill in water lily number sequences as a frog "hops" across them, skip counting by twos. There are five sequences in total, and some require counting backward. Learners can reference the two examples, which...
Curated OER
Ordering
Four sequences are missing some numbers; can your scholars fill them in? These aviation-themed number sequences require skip counting and counting backward. Beside each pattern learners can reference a jumbled set of numbers inside a...

Identifying Patterns
Investigators examine the clues to complete 17 sequences by skip counting backwards. There are two examples to get them started, and all of these patterns include the first three numbers but are missing the last five. If you want...

Revise Counting Back in Tens (2)
In this counting back worksheet, 2nd graders study the given numbers and fill in the missing numbers by counting back by tens. Students complete 6 sets.
Curated OER
Count to 200
Only 1, 2, or 3 of 15 boxes are completed in each of 5 vertical number tracks. Your pupils' challenge is to fill in the rest in sequence. Will require counting backwards; modify with number lines.

Count Back by 2
In this counting backwards worksheet, learners count back by 2 starting at 3 different sets of numbers. A reference website for additional resources is given.

Identifying Patterns
Explore number attributes and skip counting through patterns! Scholars find the pattern in each of these sequences and continue it by writing in the remaining values. They count consistently by various intervals, sometimes forwards and...
Curated OER
Counting Forward or Back
What comes next? Young counters follow the stone path to each house, filling in numbers in a sequence as they go. Some of these move forward and some backward, but all progress by ones. Learners start with given numbers and then follow...

Finding Patterns
What's the pattern? Learners skip count to complete 12 sequences, some of which increase and some of which decrease. As they solve each number pattern they count by 2, 3, 4, 5, 6, 10, and 100, getting some extra subtraction and addition...

Choral Counting I
Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...

Mentally Add and Subtract 10 or 100
Here are some number lines that need to be completed. There are two number sequences, one to test addition skills and the other for subtraction. Both sequences include counting by 10, but the subtracting question has scholars count...
