Decimal Games

A snap game matching decimals to their fraction equivalents. Builds fluency with conversions between the two forms.

Cut shapes into 10 equal parts to see tenths visually. Connects partitioning to decimal notation.

Place decimals at their correct position on a number line. Builds place value understanding and decimal number sense.

Drag decimal cards into order from smallest to largest. Sharpen place-value understanding and comparison skills.

Shade parts of a 10-strip to match the decimal shown. See how 0.3 means 3 out of 10 parts. The visual entry point to decimals.

Shade parts of a 100-grid to match decimals like 0.35. See how hundredths relate to tenths and build decimal place value understanding.

Break numbers with one decimal place into expanded form. Drag tiles like "3 ones" and "4 tenths" into the right slots.

What digit is in the tenths place? What is the value of the 5 in 3.52? Multiple choice questions building place value mastery.

Build a target decimal by adjusting ones, tenths, and hundredths. Watch the visual bar model update as you change each place value.

A student says 0.3 is bigger than 0.15 because 3 is less than 15. Wait, that is right! Or is it? Sort through tricky decimal reasoning.

Which is bigger: 0.3 or 0.7? Compare decimals with one decimal place. Visual bar models help build intuition.

Compare decimals with two decimal places. Is 0.35 bigger than 0.4? This one trips up a lot of students!

Order decimals with the same number of decimal places. A gentle introduction before mixing tenths and hundredths.

Drag the marker to place decimals on the number line. Smooth slider interaction builds decimal magnitude intuition.

A memory game matching fractions to their decimal equivalents. Flip cards and find pairs like 1/4 and 0.25.

Sort fractions, decimals, and percentages into groups of equivalent benchmark values. Match 1/2 with 0.5 and 50% by sorting cards.

Drag the slider to place decimals on a number line. Click-hold-drag interaction for maximum engagement.

Spot wrong decimal-fraction conversions. Tackles the misconception that 0.5 = 1/5.

Compare decimals visually. Tackles the misconception that more decimal places means a bigger number.

Break decimals into place-value parts. Drag tiles like 4/10 and 3/1000 into the right slots to build the expanded form of each number.

A student says 0.45 is bigger than 0.5 because 45 is bigger than 5. Can you explain why they are wrong?

Convert fractions to decimals. Start with simple ones like 1/2 = 0.5 and work up to trickier conversions like 3/8 = 0.375.

Convert decimals to fractions in simplest form. 0.6 = 3/5, not 6/10! Builds conversion and simplifying fluency.

Place fractions AND decimals on the same number line. See how they share the same positions. Builds cross-representation fluency.

Chain dominoes where one half is a fraction and the other is a decimal. Match 1/4 to 0.25, 3/5 to 0.6, and so on.
