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...

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...
Curated OER
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 activity. They fill in missing numbers on a number line to complete each sequence, adding or subtracting 10. There are two addition problems...

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 instructional activity, 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, students count back by 2 starting at 3 different sets of numbers. A reference website for additional resources is given.
Curated OER
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...
Curated OER
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...

Finding Solutions by Working Backwards
In this math worksheet, students learn to solve word problems by working backwards. Students read the 20 word problems and solve them, choosing the best answer from 4 choices. There are helpful hints on the page to clue students to work...
Curated OER
Count back 4
For this counting worksheet, students practice counting backwards by 4. They start at the specified number and count backwards by 4 one time. Students write in the number that they end up at. There are 10 problems to solve and the...
Curated OER
Counting Back in Tens
In this counting by 10's worksheet, students count backwards by 10's, starting from different 2 digit numbers. Students complete 4 problems.
Curated OER
Counting Back in Tens
In this counting backwards in tens worksheet, 3rd graders count down in tens from 80 to 30, 100 to 50, 110 to 60 and 120 to 70. Students fill in each missing number on each row.
Curated OER
Count by 5s, 10s, and 100s
These number sequences are missing digits! Each of the six has one missing number and scholars must figure out what it is. Here's the pattern, though: all of these sequences involve counting by 5s, 10s, and 100s. Learners add one of...

Number Patterns
Which number comes next? The great part about this number sequencing activity is that it increases in difficulty so some learners who aren't challenged by the first few will definitely meet their match with the last couple. In each of...
