How to use it at home and in class

At home

Learn the anchors: 50% is half, 25% is a quarter, 10% is divide by 10. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.

In class

Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.

Mistakes to watch for

• Dividing by the percentage, so 45 ÷ 20.
• Writing 20% as 2.0 instead of 0.2.

What to practice before and after percent of a number

• After: finding the percent, once this one is mostly right.
• Learn it first: the percent of a number lesson.
