Plan or Move
Middle schoolers note the similarities between decimals, fractions and percentages. They practice converting numbers between these types. They participate in an activity as well.
Curated OER
Area Applet
Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...
Curated OER
Relations
Students identify, compare, and analyze shapes and numbers. In this analogies and comparison math lesson plan, students warm up by completing 4 worksheets to familiarize themselves with analogies. In small groups, students are challenged...
