Learning Targets:
- I can use equivalent fractions as a strategy to add and subtract fractions.
- I can add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions with like
denominators. - I can use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.
- I can solve word problems involving addition and subtraction of fractions referring to the same whole.
- I can interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b).
- I can solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers.
- I can interpret the product (a/b) × q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a × q ÷ b.
In general, (a/b) × (c/d) = ac/bd. - I can find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that
the area is the same as would be found by multiplying the side lengths. - I can multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.
- I can interpret multiplication as scaling (resizing).
- I can compare the size of a product to the size of one factor on the basis of the size of the other factor, without performing the indicated
multiplication. - I can apply the principle of fraction equivalence a/b = (n × a)/(n × b) to the effect of multiplying a/b by 1.
- I can solve real world problems involving multiplication of fractions and mixed numbers.
- I can interpret division of a unit fraction by a non-zero whole number, and compute such quotients.
- I can interpret division of a whole number by a unit fraction, and compute such quotients.
