Fractions of Numbers Follow the slides

1 2 of 8 = __ Follow the step by step guide which will show you how to solve this.

1 2 of 8 = 1 Denominator 2 Split the number (that we are trying to find a fraction of) into two equal groups because the denominator is two ! Divide by this number This is the same as 8 ÷ 2 = 4 saying 8 ÷ 2 8 altogether divided by the denominator

1 2 of 8 = Numerator 1 Count up how many are in one of the groups, this is because one is the numerator Times by this number 2 This is the same as saying 4 x 1 4 in a group times by the numerator

1 2 of 8 = 4 It would look like this in your book

1 4 of 12 = __ Follow the step by step guide which will show you how to solve this.

1 4 of 12 = 1 Denominator 4 Split the number (that we are trying to find a fraction of) into four equal groups because the denominator is four ! Divide by this number This is the same as 12 ÷ 4 = 3 saying 12 ÷ 4 12 altogether divided by the denominator

1 4 of 12 = Numerator 1 Count up how many are in one of the groups, this is because one is the numerator Times by this number 4 This is the same as saying 3 x 1 3 in a group times by the numerator

1 4 of 12 = 3 It would look like this in your book

3 4 of 16 = __ Children always forget to look at the numerator! Follow the step by step guide which will show you how to solve this.

3 4 of 16 = 3 Denominator 4 Split the number (that we are trying to find a fraction of) into four equal groups because the denominator is four ! Divide by this number This is the same as 16 ÷ 4 = 4 saying 16 ÷ 4 16 altogether divided by the denominator

3 4 of 16 = Numerator 3 Count up how many are in THREE of the groups, this is because THREE is the numerator Times by this number 4 This is the same as saying 4 x 3 4 in a group times by the numerator

3 4 of 16 = 12 It would look like this in your book

Your turn! Follow to the next slide which has a variety of questions. The children can write out the question and solve it using the methods shown earlier.
