Term 2 – Numeracy

Numeracy

Over the past few weeks the school has been focusing on fractions. In Grade 5, we have covered the following:

NOTE: Each provided link is to Math’s is Fun.At the bottom of each page there are practice questions if you would like extra practice for your child.

Equivalent fractions

  • You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
  • You only multiply or divide, never add or subtract, to get an equivalent fraction.
  • Only divide when the top and bottom stay as whole numbers.

Comparing and ordering fractions

  • There are two main ways to compare fractions:using decimals, or usingthe same denominator.
  • We have to convert the fractions to the same denominator in order to compare.

Proper and Improper fractions, mixed numbers and simplification of fractions

Proper fraction – has a top number less than its bottom number

Improper fraction – has a top number larger than (or equal to) the bottom number.

Mixed numbers – a whole number and a proper fraction combined.

Simplification of fractions – To simplify a fraction, divide the top and bottom by the highest number that can divide into both numbers exactly.

Adding and subtracting like and unlike fractions

  • When we add or subtract fractions, the denominators must be the same.
  • First add or subtract the whole numbers, then if required, convert mixed number to improper fraction.
  • Our final answer must be simplified.
  • All working out must be shown.
