## Which Fraction is bigger?

**Before doing the task….. YOU and other teachers DO THE MATHS**

Have your students sitting as a group. Ask them which Fraction do you think is bigger?*Get them to move to that side of the room.*

Now that the students have decided, get them to justify their answer and challenge each others thinking. *This is where the fun begins. In a safe environment students will challenge, prove and change sides and ideas. *

Continue to probe students to share their thinking. *Some students can draw what they are thinking to help explain their idea. The aim is to convince the other students that you have the correct answer.*

**Results:***When I did this lesson in a Grade 5/6 classroom some wonderful learning occurred. 27 students went to the 1/2 side and one student stayed with 100/199. **After 20 minutes and a discovery session that one student stayed with 100/199 and was correct.*

**Fractions as a collection: **If there are 199 students at the school and 100 of those students are boys. Then there is 1 more boy than girls. Therefore 100/199 is more than one half.

**Fractions as division: **1 divided by 2 equals 0.5. 100 divided by 199 is 0.5025

**Fractions as decimals: **When made into decimals 1/2 is 0.5 and 100/199 is 0.5025. This is a good time to bring out your decipipes and show student what a visual representation of a decimal is.
