Maths

Each week in your Maths home learning there will be two different types of activities.  There will be a main key objective and a Maths fluency key objective.  The main objective this week is to add and take away fractions.  The Maths fluency key objective is to identify prime numbers.  Remember to keep working on your times tables using Times Tables Rockstars.

There are fraction activities available in the homework section on Education City,  In addition have a look at the fractions activities on the Mathletics website.

Each Friday we will post the answers to the challenges.

KO: To add and take away fractions

Below there is a video that explains the rules for adding fractions when the denominator of both fractions is the same.

The most important thing to remember for both adding and taking away fractions is when the denominator is the same for both fractions, then the answer will have the same denominator.
