Fraction Equivalence, Ordering, and Operations
Need a unit to teach fractions to fourth graders? Look no further than this well-developed and thorough set of lessons that takes teachers through all steps of planning, implementing, and assessing their lessons. Divided into eight...
Curated OER
Matching Directions
These abstract shapes are pointing in different directions and young scholars determine which ones are oriented the same way. For each of five starting shapes they examine a set of four identical figures pointing in various directions,...
Curated OER
Matching Directions
Which of these shapes is pointing the same way? Pre-readers examine five rows of familiar objects. The first item points to the right for each, and they must determine which of the subsequent items in each row points the same direction....

Create and Understand Box-and-Whisker Plots: Babies in a Waiting Room
Explore the strengths and weaknesses of box-and-whisker data display. An interactive lesson asks learners to create a box-and-whisker plot from a set of data. Challenge questions focus on determining what types of conclusions they can...
Curated OER
Match the Shapes
Which shape is the same? Young geometers match a triangle, circle, rectangle, and square to their identical counterparts, connecting them with a line from left to right. Then, they do the same thing with a set of four circular shapes,...
