A comprehensive overview of math concepts and skills for Primary 3 students preparing for the ISEE.
Fractions show parts of a whole, like slices of a pizza.
A fraction has two numbers: the top number (numerator) tells how many parts you have, and the bottom number (denominator) tells how many parts make a whole.
When you cut a sandwich in half and eat one piece, you’ve eaten \( \frac{1}{2} \)! Fractions help with recipes, sharing, and measuring.
The bigger the denominator, the smaller each piece. Practice comparing and recognizing common fractions like halves, thirds, and quarters.
1/4 of a chocolate bar means 1 piece out of 4.
3/8 of a pizza means 3 pieces out of 8.
Fractions help us talk about parts of things.
