LO: I can add fractions with the same denominator.


Today we are going to work through some questions with fluency, reasoning and problem solving when adding fractions.

When you add fractions with the same denominator, you add the numerators together and the denominator stays the same. You do not add the denominators together.

E.g.   4/10 + 2/10 = 6/10












As you can see I have coloured the first 4 of the bar model, then 2 more but the amount of sections in the bar model stay the same. I now have 6 of the 10 sections coloured in. 6 tenths.
