As an introduction to our unit on surface area and volume of solids, my students investigated cross-sections of solids through a Play-Doh Cross Sections lab activity. Materials: play-doh, paper plates, dental floss, plastic knife, and ruler.
A great math activity idea that revolves around using Play-Doh to help students learn about solid cross-sections. I've always had a hard time visualizing these types of things, and I wish my teachers had used this lesson idea! I can't wait to try it!
Let us climb peaks by all means, because their beauty attracts us; not because others have failed, nor because the summits stand 28000 ft above the sea…Let us approach the peaks with humility, and through finding the way to them…learn to solve their problems.
Eric Shipton (1938)
A great math education blog that contains reflections on being a teacher and great resources to use in the classroom, including lesson ideas and book reviews!
