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...
CK-12 Foundation
Stratified Random Sampling: An Extracurricular Study
Learning isn't a random process. A well-designed interactive lesson helps classes make key conclusions about stratified random sampling. They calculate group percentages and use those percentages to decide on sampling totals.
CK-12 Foundation
Zeroes and Intercepts of Polynomials: Function Intercepts
There is zero reason not to use the resource. Given a graph with a polynomial function and a linear function, scholars move the line in an interactive. To wrap up the lesson, they note how zeros and intersection points change.
CK-12 Foundation
Proportions and Scale: Problem Solving Plan, Proportions
Slide into a lesson on proportions. A slider interactive lets users adjust three of the four values in a proportion and automatically updates the fourth value. Scholars use the interactive to help answer a set of challenge questions on...
Curated OER
Geometry
Fourth graders explore symmetry and congruent figures. They draw letters of the alphabet that have symmetry, draw congruent figures, draw figures on dot paper, and complete three worksheets.
