Third graders become more familiar with various geometric shapes by completing the games and activities in this lesson. They keep track of the number of each shape they use in each of the three ways.

Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the instructional...

Third graders are asked how multiplication, division, addition and subtraction are related. After being read part of a book, they work together to build a model between addition and multiplication. To end the lesson, they write about...

Sixth graders are introduced to the concepts of area and volume. In groups, they work together to build models of square centimeters in which they are given no instructions. To end the activity, they record the dimensions of each model...

Fourth graders predict, observe, and compare what happens when a force is applied to an object. In this forces lesson, 4th graders complete a 'swinging hammer' activity to learn about forces and motion.

First graders measure a plant using unifix cubes and record their measurements on a class chart.

Second graders investigate sodium content in the foods that they eat.

First graders play a Hawaiian counting game. They use a worksheet to play a game of Lu-Lu at school and then take home a sheet to play with their families.

Students connect the numeral to an appropriate quantity of M&M candies.

Fourth graders interpret the weather data they gathered in Investigation 6. They take an average of each component in each season. They compare the same components of each season and write the differences they see between the seasons.

Third graders measure the heat created at each center.

Students develop a month long budget. They use problem solving skills to adjust their budgets for unforeseen expenses. They use checks to pay mock bills.

First graders experience addition through the exploration of a virtual pond. They categorize the various plants around the pond, count the number of various types of plants on the pond shore, and calculate the number of shrubs.

Third graders cut a map of a pond into grid squares. They count the total number of squares and calculate the probability of drawing a pond piece vs. a shoreline piece. They draw 10 pieces and compare the results with the original...

Students demonstrate their ability to collect, organize, and display data. They examine everyday objects that can be turned into a function machine for the lesson. They use colored fish to help them organize their data.

Students discuss and create their own patterns. They practice and improve on making patterns of their own using red, white, and blue paper for a national theme. The symbols are based on what the teacher picks for the class.

First graders practice identifying simple geometric shapes. As a class, they discuss positional words and review the words for simple shapes and their characteristics. They work together to create their own puzzle using the shapes.

Third graders engage in a lesson that is concerned with the playing of a Trick Triangle Game while focusing upon developing skills of addition, subtraction, multiplication, and division. They play the game and practice rounding of...

Using the Hudson River as the focus, learners discuss the difference between salt water and fresh water environments, analyze maps and graphs, and complete addition and subtraction problems. This lesson comes with a wealth of...

Students practice using a GPS receiver. They walk in different directions and monitor their progress on maps. They enter specific locations and use information given to them to get them back to their original locations.

Tenth graders investigate the circumference and diameter of a circle. In this geometry lesson, 10th graders relate circumference to diameter. They create a scatter plot to estimate the value of pi.

Students explore the three dimensional Cartesian coordinate system and discuss how it is important for structural engineers in order to be able to describe locations in space to fellow engineers. They participate in a hands-on activity...

Students create two drawings for a new animal pen design at the zoo. They must draw the ideas keeping the amount of material available in mind. They compare and contrast their two designs and write how they are similar in perimeter and...

Learners place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.
