Fractions with Linda and with Bryony from Waitakere College
Discussed common misconceptions in students understanding of fractions and how to teach.
Eg. 2/5 + 4/5 = 6/10
1/2 = 0.2
1/4 is bigger than 1/2.
Bryony reminds us that teaching that fractions are equal parts is so important for students to understand from the very beginning.
Idea:
Fold a piece of paper in half. Cut out a border from a blank piece of paper. Cut strips from the middle bit. Use to show and visualise halves, quarters etc. Can put equipment in the sets so they can see 3/4 of a set of 12 etc.
For teaching and introducing decimals go to NZ Maths and download the decimats.

Bryony introduced the double number line for teaching ratios. Possibly stay away from the 1:2 ratio as students just think it's half.
Looked at Mixing Colours - Pink Book Number 7, Pg 50. Ratio's and colours.
