The Power of Algebra
First graders explore patterns. They look for patterns in number problems and use algebra as a means of solving general problems. Students devise a strategy to solve the number problem.
Curated OER
Linear Functions: Are You Ready for the REAL World?
students emulate a real world problem and model it with mathematics working in a small group. Observe and facilitate discussion as the groups use various strategies, such as (graphs, brainstorming, tables, and dialogue.
Curated OER
Fibonacci I
Fifth graders have the opportunity to gather information themselves on Fibonacci and on the occurrence of Fibonacci numbers in nature. They divide up into groups of 2 to 4 to research.
Curated OER
Tukutuku Patterns
Students complete a series of lessons involving Tukutuku patterns, their rotations and area formulae. They determine the algebraic formulae for sequences. They use images as they work through the lessons to find the number of crosses in...
Curated OER
Visualizing Integers
Students create visuals on the TI Calculator to solve problems. In this algebra lesson, students perform basic operations with integers. They add, subtract, multiply and divide.
Curated OER
Rusting-A Form of Oxidation
High schoolers observe the rusting process in the lab. In this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.
Curated OER
Squirt
Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...
Curated OER
Squirt Level 3
Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...
Curated OER
Bubble Gum Chemistry
Students explore the concept of graphing data. In this graphing data lesson, students determine the percentage of sugar in bubble gum. Students graph type of gum vs. sugar percentage. Students create a table of their data.
Curated OER
Natural Selection
Students practice calculating allele and genotype frequencies in the framework of a simple simulation using hard candy, calculators, and a worksheet. This lesson plan includes a three-page worksheet and an assessment question for...
Curated OER
Not Your Average Average
Students discover that if a distance is traveled in two or more segments at different average speeds, you cannot average the average speeds. Instead the total distance traveled must be divided by the total elapsed time. Students practice...
Curated OER
Rusting: A Form of Oxidation
Pupils observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.
Curated OER
Flying With Mathematics!
Third graders fly miniature airplanes to discover characteristics related to velocity and average speed. After measuring the time and distance of their flights, 3rd graders calculate the average velocity of their planes.
Curated OER
Testing the Accuracy of a Rain Gauge
Middle schoolers identify and test variables that may affect the accuracy of a rain gauge.
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
