Multiplication and division:

• multiplication facts, division facts, or both mixed together
• practice all tables from 1 to 10, tables 1 to 5, tables 6 to 10, or a single table like the 7s
• missing factors, like 6 × ☐ = 42 or ☐ ÷ 4 = 7
• equal groups and arrays with pictures, like 3 groups of 4 = 12
• multiplying by multiples of 10, like 9 × 80

Numbers and operations:

• rounding to the nearest 10 or 100, including halfway numbers like 45 and 350
• adding and subtracting within 1,000, with regrouping, without regrouping, or a mix

Fractions:

• naming fractions of shaded circles and rectangles, from halves to eighths
• fractions on a number line from 0 to 1
• comparing fractions with the same numerator or the same denominator
• equivalent fractions with fraction bars, like 1/2 = ☐/4

Measurement:

• perimeter of rectangles, triangles, and other polygons, in cm, in, m, or ft
• elapsed time, like “Recess starts at 2:15. What time will it be 35 minutes later?”

Set up the worksheet:

• problems written in a row, or stacked
• colorful pictures, or turn the colors off to save ink
• 6 to 30 problems per worksheet, and your own worksheet title

Answer keys:

• printed on a separate page, so students don’t see the answers
• carried digits shown for stacked addition problems
• print the answer key on its own, or save both pages as a PDF

Worksheet code and sharing:

• every worksheet has a code printed at the bottom
• enter the same code and settings to get the exact same worksheet again
• no need to save worksheets: just write down the code to reprint a copy or find the answer key
• click “Share worksheet” to send a link with the same problems to another teacher or a parent
• click “New worksheet” any time for a fresh set of problems

Use these worksheets for classwork, homework, math centers, quizzes, or extra practice. Since every worksheet is new, students can practice each skill as many times as they need.
