Squares, rectangles and triangles, Oh my!! First and Second grade students had a blast engineering igloos during STEM Lab. First, students practiced making different shapes in a blank document. Students were able to put to use the skills learned during our previous class project. Next, the students filled the shapes with color, outlined shapes and then practiced making the shapes different sizes. Finally, students set off to engineer a 3D igloo. We had a blast engineering and designing our igloos. Take a look!
