Explain and/or illustrate why two fractions are equivalent.

Recognize and generate equivalent fractions.

Explain why a fraction π’/π£ is equivalent to a fraction (π― Γ π’)/(π― Γ π£) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Explain why a fraction π’/π£ is equivalent to a fraction (π― Γ π’)/(π― Γ π£) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Explain why a fraction π/π is equivalent to a fraction (π Γ π)/(π Γ π).

Explain why a fraction π’/π£ is equivalent to a fraction (π― Γ π’)/(π― Γ π£) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Using visual fraction models, explain why a fraction π’/π£ is equivalent to a fraction (π― Γ π’)/(π― Γ π£). Use this principle to recognize and generate equivalent fractions.

explain why a fraction a/b is equivalent to a fraction (n Γ a)/(n Γ b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size and use this principle to recognize and generate equivalent fractions.

Explain why two or more fractions are equivalent π/π = (π Γ π)/(π Γ π) ex: 1/4 = (3 Γ 1)/(3 Γ 4) by using visual fraction models. Focus attention on how the number and size of the parts differ even though the fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
