Quadratic Functions: Toothpicks and Transformations
Source Institutions
In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.
Solving Linear Equations: The Yo-Yo Problem
Source Institutions
In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.
Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.
Sweetly Balanced Equations
Source Institutions
In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.
Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Looking Through the Algebraic Lens
Source Institutions
In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.
Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
Filling the Time
Source Institutions
Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done?
Sweet Measurements
Source Institutions
In this activity on page 3 of the PDF, learners investigate how much sugar is in a soda. Learners use sugar cubes to measure and calculate the amount of sugar in a bottle of soda.
Playground Patterns of Cracks
Source Institutions
In this math activity, learners observe and sketch cracking patterns in pavement.
Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.
Phylogenetics
Source Institutions
This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.
Read With Your Fingers
Source Institutions
In this activity, learners work in partners to create and exchange messages written in Braille. Learners use a Braille key and thumbtacks to write their messages in Braille.
Narrow it Down: Numbers
Source Institutions
In this activity, learners will ask yes-no questions to identify a secret number (similar to Twenty Questions). Combine logic and numbers in this game for all ages.
Mass of the Earth
Source Institutions
In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.
Handy Measuring Ratio
Source Institutions
In this activity, learners use their hands as tools for indirect measurement.
Algebra: Aw Chute!
Source Institutions
In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.
Sleep Patterns
Source Institutions
In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.
Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.
Rates of Change: Bottles and Divers
Source Institutions
In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.
