Numbers, shapes, and fractions. Open a lesson below, then check the resources or try the quiz.
A fraction shows a part of a whole. It has two numbers: the top number (numerator) tells how many parts you have, and the bottom number (denominator) tells how many equal parts the whole is split into. If you eat 3 slices of a pizza cut into 8 slices, you ate 3/8 of the pizza.
Think: numerator = slices you took, denominator = slices total.
When two fractions have the same denominator, just compare the numerators — the bigger numerator is the bigger fraction. 3/8 is bigger than 2/8. When denominators differ, imagine cutting both wholes into the same size pieces first.
Same bottom number? Compare the tops!
To add fractions with the same denominator, add the numerators and keep the denominator the same: 1/5 + 2/5 = 3/5. The whole doesn't change size — only how many pieces you're counting.
Keep the bottom, add the top.
Multiplication is repeated addition. 4 × 3 means '4 groups of 3' or 3+3+3+3 = 12. Learning your times tables up to 12 makes division, fractions, and everyday math much faster.
4 groups of 3 apples = 12 apples.
