- Explain why two fractions are equivalent by comparing the shaded areas

Equivalent fractions are fractions that look different but stand for the same amount. If you split a shape into more equal parts and shade more of them to match, the amount you shaded stays the same.
Mia has a chocolate bar split into 2 equal parts and eats 1 part. Zara has the same size bar split into 4 equal parts and eats 2 parts. The bars look different, but both girls ate the same amount.
To check if two fractions are equivalent, do not just look at the numbers. Compare how much space is shaded. If the shaded space is the same size, the fractions are equivalent.
Same amount, more parts: that is what makes two fractions equivalent.

Equivalent fractions review
Equal fractions are the same amount wearing different costumes. One half of a pizza covers exactly as much as 2 quarters of the same pizza. Cut each half into 2 and the 2 halves become 4 quarters, with 1 half matching 2 quarters. Shade both forms on paper plates and hold them against the light.
Visualizing equivalent fractions review
Doubling the cuts doubles both numbers but keeps the value frozen. Two thirds sliced again becomes 4 sixths: same shaded dinner, thinner slices. Build it with a fraction wall: lay 2 thirds on the top row and 4 sixths below, edge to edge. Matching lengths prove the match.
4.2: Equivalent Fractions
Two fractions match when their shaded areas match. Lay 3 quarters over 6 eighths and the borders line up exactly, proving 3/4 equals 6/8. Multiply top and bottom by the same number to travel between matching forms. Test every claim with shaded bars before trusting the arithmetic.
