Understand decimals (tenths and hundredths) and relate them to fractions
Cut one whole into 10 equal parts for tenths, or into 100 for hundredths. Every decimal has a twin fraction: 0.3 = 3/10 and 0.37 = 37/100 — same amount, two names.

Kavi's Two-Name Numbers 🍫
Kavi snaps a chocolate bar into 10 equal pieces and eats 3 🍫. "Three tenths — 3/10 or 0.3," hoots Kavi. Then she slices each piece into ten tiny squares: 100 in all! "Now I can count hundredths too — 37/100 = 0.37. Every decimal has a twin fraction!"

What your child will learn
1Cut one whole into 10 → tenthsCut a whole bar into 10 equal parts and shade 3. Each part is one tenth. The readout shows 3/10. The first place after the decimal point is the tenths place, so we also write this as 0.3.
2Shade your own tenthsHere is a circle cut into 10 equal parts. Tap to shade 7. The readout shows 7/10 — seven tenths. As a decimal that is 0.7.
3Cut each tenth into 10 again → hundredthsSlice every tenth into ten tiny parts. Now the whole is in 100 equal parts — each one is a hundredth. Tap each card.
4Tenths place and hundredths placeA decimal like 0.46 has two places after the point. Tap each card to read it, then write its twin fraction.

A peek inside
Kavi shades 3 of 10 equal parts 🍫. Write it as a fraction and a decimal.
3 shaded out of 10 → 3/10 → point, then 3 → 0.3
