Nice warm-up
A bit trickier
Go for it!
Build decimal number fluency through targeted practice. Children learn to read, compare, and perform calculations with decimals, connecting them to fractions and place value. This bridges the gap between whole-number arithmetic and the decimal system used in real life.
Line up the decimal points when comparing or adding decimals. Each place to the right of the point is ten times smaller: tenths, hundredths, thousandths.
Money, race times, and weather temperatures use decimals. Place value after the point keeps cents and millimetres honest.
Who it suits: Decimals games are most appropriate for Grades 4-7 (ages 9-13). Grade 4 learners typically begin with tenths and hundredths. Grade 5-6 learners extend to thousandths and decimal arithmetic. Grade 7 learners use decimals in more complex calculations including percentages and ratios.

Select your difficulty, then solve decimal problems by choosing the correct answer. Questions progress from reading decimals to calculating with them.

Decimals are the number system of everyday life — prices, measurements, statistics, and scientific data all use decimal notation. Children who are comfortable with decimals can interpret real-world information far more confidently than those who find them confusing. Decimals also bridge whole numbers and fractions, and children who understand all three representations have a much more flexible number sense.

The classic decimal misconception is that more digits after the decimal point means a larger number (so children think 0.35 is bigger than 0.8). This comes from treating decimal digits like whole numbers. The fix is to read decimals column by column: compare the tenths digits first. Since 8 tenths is more than 3 tenths, 0.8 > 0.35. Using a place value chart with labelled columns — ones, tenths, hundredths — makes this comparison process explicit and reliable.
