Addition & Subtraction Worksheets

Add two groups of pictured objects — within 5 or within 10.

Take away pictured objects to subtract — within 5 or within 10.

Solve one-step add-to, take-from, and put-together word problems with totals within 10 — with counters to count, or words only.

Break the same number up to 10 into two parts more than one way, shown with red discs and yellow squares (5 = 3 + 2, then 5 = 4 + 1).

Complete each number bond: a whole breaks into two parts that add up to it. Count the two-color dots, then write the missing number.

A ten-frame shows the known part as solid circles and the missing part as dotted circles; fill in the number that makes 10.

Adding two single-digit numbers whose sum is 5 or less, the earliest fluency milestone.

Take-away subtraction with both numbers 5 or less and no negative results.

Solve add-to, take-from, put-together, take-apart and compare word problems within 20. Pick one situation to drill, or mix them; the answer can be the result or an unknown operand shown with a box.

Solve word problems that add three whole numbers with a total within 20. Look for two numbers that make ten first, then add the third.

Summing three single-digit addends with a total up to 20, using grouping strategies.

Apply properties of operations to add: add in any order — count the pictures, write the turnaround fact, or fill the missing number — and group the two numbers that make ten first.

Understand subtraction as a missing addend: find 10 - 8 by asking what adds to 8 to make 10.

Relate counting to addition: start at the first number and count on, and the last number you say is the sum.

Add within 10 or 20.

Subtract within 10 or 20.

Add or subtract within 20 on a double ten-frame: make a ten to add, read two near-ten addends as 10 minus their empty cells, or take the subtracted number from the full ten.

Part-part-whole number bonds for wholes from 11 to 20: fill in the missing part or the missing whole. The Singapore-style bond behind adding and subtracting within 20.

Use a number line to add and subtract within 20. Draw the jump yourself, or read a jump that is already drawn: start at the number shown and say where it lands.

Decide whether an equation is true or false. The equal sign means both sides are worth the same, so equations like 5 + 2 = 2 + 5 and 7 = 8 - 1 count too.

Complete each fact family house: the roof shows the whole and its two parts. Write the two addition and two subtraction facts on the lines.

Find the unknown number in an addition or subtraction equation, within 20. The box can be in any position: 8 + [] = 13, [] - 5 = 4, 6 + 7 = [].

Add within 100 — a two-digit number plus a one-digit number, a whole ten plus ones, a two-digit number plus a multiple of ten, two multiples of ten, or two two-digit numbers (with or without composing a ten).

Subtract within 100 — a two-digit number minus a one-digit number, a two-digit number minus a multiple of ten, two multiples of ten, or two two-digit numbers (with or without regrouping).

Use addition and subtraction within 100 to solve one- and two-step word problems — adding to, taking from, putting together, taking apart, and comparing. Use the Focus buttons to choose one-step or two-step problems.

Fluently add and subtract within 20 using mental strategies, and know from memory all sums of two one-digit numbers. Choose addition, subtraction, or a mix of both.

Bridge through a ten - break a number so you reach a ten first, then finish. Works within 20 (8 + 5 = 8 + 2 + 3 = 13; 13 - 5 = 13 - 3 - 2 = 8) and within 100 (28 + 5 = 28 + 2 + 3 = 33; 32 - 5 = 32 - 2 - 3 = 27).

Enrichment: rebuild column additions where most digits are hidden. Every puzzle has exactly one solution — use place value and regrouping clues to fill in the boxes.

Enrichment: rebuild column subtractions where most digits are hidden. Every puzzle has exactly one solution — use place value and regrouping clues to fill in the boxes.

Represent whole-number sums and differences within 100 on a number line diagram; jump by tens and then by ones, then write the answer.

Add multi-digit whole numbers. Use the Focus buttons to set the number of digits, turn regrouping (carrying) on or off, add three numbers, or switch to column form.

Subtract multi-digit whole numbers. Use Focus to set digits, regrouping, column form, or a missing number.

Add several numbers by choosing a smart order or grouping: look for two numbers that are quick to add first, then add the rest.

Add three or four two-digit numbers with column (vertical) addition: line up the ones and tens, add each column, and carry — building fluency.

Add and subtract using the column (vertical) method, lining up digits by place value.

Subtract across zeros — the standard way, from 100, and with mental strategies: count up, think addition, and a no-regrouping trick.

Show each 3-digit number with base-ten blocks, then add or subtract — deciding when to regroup.

Add three-digit numbers by place value using expanded form and partial sums.

Add or subtract 10 or 100 to a three-digit number in your head, and say which digit changes and why the others do not.

The constant-difference (“same difference”) mental strategy: slide both numbers up so the number you subtract lands on a ten, and the difference stays the same — 62 − 38 = 64 − 40 = 24. Taught with the Age-Gap detective lab.

Explain why an addition or subtraction strategy works — place-value splitting, making a ten, adjusting, or same difference — and find the mistake when a strategy is used wrongly.

Fluently add and subtract within 1000 with mental strategies — making a hundred (compensation), counting up to subtract, and fact families — using place value, properties, and the relationship between addition and subtraction (beyond the column algorithm).

Add several numbers within 1000 by choosing a smart order or grouping: find two that are quick to add first, then add the rest.

Add and subtract two 4-digit numbers using the column (long) method: line up the digits by place value and regroup.
