Third graders explore signs and vocabulary linked to the work of Keith Haring.

Third graders draw and interpret simple scale maps, use maps to move around efficiently or plans to propose actions. They use of a compass to specify and find directions. They display and discuss a map of the local region.

Students describe three different categories to sort into. They sort these clothes into these three chosen categories. After asking questions the student divide the clothes.

Students use an Internet tool, The Take-Away Bar" to solve subtraction problems. They use mental strategies to subtract a two-digit number from a larger two-digit number. Students write and solve subtraction problems. They describe...

Young scholars cut out a large rectangle from brown paper with scissors. They fold the narrow end up, leaving room for a flap at the top and have the teacher staple the edges of the pouch together. They then decorate their pouch with...

Fourth graders examine how to determine the probabilities or likelihood of outcomes. They complete trials to determine probability while using different manipulatives. They determine how games can be made fair or unfair in this unit of...

In this activity, students see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float. This high-volume but light-weight material increases...

Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...

In this activity, students use the Geoboard App to draw and make a reflection of a scalene triangle. [Requires Adobe Reader.]

In this activity, students will understand the basic geometric concepts of parallelism and perpendicularity, and will also able to use rectangular coordinates to make congruent objects. They will display understanding of parts of...

"The volume of a cube can be developed by considering unit cubes, a single row (longs) of unit cubes or a single layer (flats) of cubes using this applet." This easy software makes it possible to easily construct a cube and take it...

NASA has made predictions that by 2036 a quarter-mile-wide asteroid named Apophis could possibly collide with Earth. This site outlines what preventative measures scientists are taking to avoid this impact.

This lesson plan is a unique and fun way to review perimeter, angles, and types of adjectives. Students pick an object from the classroom that will fit in a paper lunch bag. They investigate their object and fill in the attached sheet....

View the museum object record for a Henry rifle given to Lincoln at the start of the Civil War. Record includes a history of the firearm, making note of its design as the inspiration for the famously successful Winchester rifle that came...

In this activity, Students can use a Force Sensor to measure the force needed to lift an object and the force needed to pull the same object up an inclined plane. They will also calculate work done and efficiency and make conclusions.

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you...

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

Students will record the sound that ten different objects make when they are dropped. The students will then use those sounds to create multiplication problems for other students to answer.

Through this lesson students will sing and recognize high and low sounds and sort pictures of objects that make high or low sounds.

Practice your underhand throw has you toss various object into a "Wishing well." As your throws improve, move further away from the wishing well or make the wishing well smaller to increase the difficulty of the activity.
