The San Diego Math Network, funded by a generous donation from the Gates Foundation, provided funding for sixth grade math teachers from across the district to participate in planning a ratios, rates and percents unit led by Math Transformations. The teachers worked together and deepened their knowledge of best strategies for helping students make sense of ratios using cuisenaire rods. Cuisenaire rods are a manipulative used in math classes to help students visual and understand math concepts. The teachers in this group enjoyed expanding their skills and working together to develop a well-balanced, engaging unit around ratios, rates, and percents that they can't wait to teach!
