Journey North
Third graders study butterflies and their migration habits. They track butterfly migration and communicate via e-mail with students in Mexico where the butterflies migrate. They write letters to the students in Mexico, as well.
Curated OER
Inventors Timelines
Students create a class timeline using the patent year for their selected inventor or invention. Using a piece of yarn, they physically create a timeline, and create and answer math word problems using the years from the timeline.
Curated OER
Fast Food Survey Using Bar Graphs
Second graders conduct survey and sort data according to categories, construct bar graph with intervals of 1, and write a few sentences about their graphs.
Curated OER
Noughts
Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.
