In this 6th grade math lesson the students begin the understand ratio’s and proportions reasoning. It starts out with the teacher showing how to make the perfect purple paint. She demonstrates this by using measuring cups and tubs of water, one blue and one red. She explains the ratio is 2 cups blue to 3 cups of red for each batch of paint. Then she states the students have blocks are their group tables and instructs them find different ways to model a 2 to 3 ratio using a total of 20 blocks. Within their groups they were told to discuss and explain why they chose that of group their blocks. By doing this activity the students are introduced to ratio’s and proportions. Also to the understanding of comparing of two different amounts.
