Everyone does their fair share. The sixth segment in a 22-part unit presents the mean as a fair share. Groups build a conceptual understanding of the mean of a data set, rather than simply learn an algorithm. Learners use the...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Making groups of groups can help to organize data. Classes use statistics to group themselves using descriptive adjectives. The objective is for learners to understand that grouping qualitative data is useful when the original groups are...

Fe, phi, fo, fum. This activity leads pairs to find the ratio of consecutive terms of the Fibonacci sequence. The pairs find that the Fibonacci sequence can be found in many places. A discussion with the class shows that the ratios...

How much rain can that cloud make? Through a simulation, the class estimates the amount of candy rain contained in different cup clouds. After probing the clouds using different methods, class members adjust their estimates. Participants...
