All vs. Only Some
All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...
Curated OER
Time
Here, learners review telling time using an analog clock. They use a clock to tell time, make a paper clock, and discuss the concept of elapsed time. However, the lesson is not always easy to follow, nor are the questions clear.
Curated OER
Just a Minute!
Students put the standard measure of clock time -- the minute -- in perspective. This lesson can be modified for virtually any grade level. They write about what they learned about a minute as a result of the activities.
