5th grade decimal operations videos

Quick answer

In 5th grade (ages 10–11), children add, subtract, multiply and divide decimals to hundredths. Start with Math Antics "Decimal Arithmetic", then step-by-step Math with Mr. J lessons, Khan Academy decimal grids and Numberock songs. Play all on repeat for a review block, or loop one worked example until it clicks.

What does this 5th grade decimals unit cover?

It covers lining up place values to add and subtract decimals, multiplying a decimal by a whole number or another decimal, and dividing decimals by whole numbers and by decimals. By the end a child should solve 3.6 × 0.4 and 7.2 ÷ 0.3 and explain where the decimal point goes.

How does RepeatWatch help with decimal problems?

Set an A–B loop on one worked example and copy it onto paper step by step. Slow a tricky step, like moving the decimal point in a divisor, to 0.75×. Save the adding, multiplying and dividing parts on keys 1–9, and use Repeat one on a Numberock song.

Frequently asked questions

What grade learns to multiply and divide decimals?

In the US, operations with decimals to hundredths are usually taught in 5th grade (ages 10–11), building on 4th grade tenths and hundredths. Grade levels vary by country and school, so start wherever your child is.

How can we keep a decimals session short?

Pick one operation per session: watch one lesson, loop the example, then try three problems on paper. Use Stop after N loops so a video ends on its own. Videos play in YouTube's player, so YouTube may show ads.
