Children's Museum of Houston - Pre/Post Classroom Activities - Nets
Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

Solving Fractions with Manipulatives
Students use candy bars, beef jerky, and brownies to represent different fractions. Students also use colored multi-link cubes or blocks to illustrate the same representations of fractions. Students work with a partner to create diagrams...
Curated OER
Teaching with Collections
Students examine collections. In these real-world collections lessons, students examine and describe buttons and shells. Students will then sort, classify, and graph items according to various indicated descriptors.
Curated OER
Equations in the Park
Students explore algebraic concepts using real life situations. In this equations lesson, students develop strategies to solve missing number problems. Students participate in a board game based on algebraic equations.
Curated OER
Guess My Rule
Students drill on math patterns, functions and Algebra. They construct and use tables to solve problems associated with mathematical relationships and identify a rule/equation. Students comprehend input/output to determine the...
Curated OER
Fractions Continued
Students investigate the concept of using fractions to solve problems involving rational numbers. They order real numbers on the number line with the classification of fractions. Also students solve problems using the four operations...
Curated OER
Describing Patterns
Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.
Curated OER
Measuring the Area of Polygons
Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...
Curated OER
Fractions and Halves
Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.
