Rational Numbers


Learning Target 1:

I can recognize and create equivalent fractions. This means I can...
  • create equivalent fractions by using visual models.
  • explain how two fractions that look different may be equivalent.
  • explain how the number and size of the parts of two equivalent fractions are related.
  • explain why two fractions are equivalent by using visual models.
  • create an equivalent fraction by multiplying the numerator and denominator by the same whole number (other than zero).

Learning Target 2:

I can compare fractions referring to the same or equal wholes. This means I can...
  • use benchmark fractions, common denominators or common numerators.
  • arrange fractions in order on a number line (including a line plot)
  • record fraction comparisons by using symbols (<, =, >)

Learning Target 3:

I can explain how fractions and decimals relate to each other. This means I can...
  • explain that decimals are another way to write fractions.
  • write a fraction with a denominator of 10 or 100 as a decimal.
  • express a fraction with a denominator of 10 as an equivalent fraction with a denominator of 100.
  • add two fractions with denominators of tenths and hundredths.

Learning Target 4:

I can compare decimals referring to the same or equal wholes. This means I can...
  • explain how the place value system for whole numbers extends to decimals.
  • compare decimal numbers to hundredths by reasoning about their size.
  • arrange decimals in order and record decimal comparisons by using symbols (<,=,>).

Learning Target 5:

I can add and subtract fractions (including mixed numbers) with like denominators. This means I can…
  • explain with diagrams, words and numbers that addition and subtraction of fractions is joining and separating fractions that refer to the same or equal wholes.
  • use addition and subtraction strategies based on properties of operations and the relationship between addition and subtraction to solve problems.
  • replace mixed numbers with equivalent fractions, when needed, in order to add and subtract them.

Learning Target 6:

I can multiply a fraction by a whole number. This means I can…
  • interpret a product of a whole number and fraction as a combination of equal groups.
  • represent a fraction as a multiple of unit fractions by using visual fraction models and equations.
  • represent multiplication of a fraction by a whole number using visual fraction models and equations.

Learning Target 7:

I can solve word problems involving fractions. This means I can...
  • represent and solve word problems by using visual fraction models, line plots, and equations.
  • solve word problems involving the addition and subtraction of mixed numbers with like denominators where the fractions refer to the same or equal wholes.
  • solve word problems involving multiplication of a fraction by a whole number.
