In 4th grade (ages 9–10), children multiply up to four-digit numbers by one digit and two-digit numbers by two digits. Start with Math Antics "Multi-Digit Multiplication", then area model and box method lessons from Math with Mr. J and a Numberock song. Play all on repeat, or loop one worked example.

What does this 4th grade multiplication unit cover?

It introduces multiplying by multiples of 10, the distributive property, the area model and partial products, then the standard method for 3-digit by 1-digit and 2-digit by 2-digit problems. By the end a child should multiply 34 × 27 and explain each partial product.

How does RepeatWatch help with long multiplication?

Set an A–B loop on one worked example and copy it step by step on paper. Slow a tricky regrouping step to 0.75×, save the area model and standard method parts on keys 1–9, and use Repeat one on the Numberock song for practice.

Frequently asked questions

What grade learns multi-digit multiplication?

In the US, multiplying up to 4-digit by 1-digit and 2-digit by 2-digit numbers is usually taught in 4th grade (ages 9–10), and fluency with the standard method comes in 5th grade. Grade levels vary by country and school.

Why learn the area model before the standard method?

The area model shows why multiplication works: each box is one partial product, using place value. Once a child sees that, the shorter standard method makes sense. Stop after a few loops of a video, then practice two or three problems on paper.
