The purpose of this task is to give 4th grade students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90_ and that angle measure is additive.

This short video and interactive assessment activity is designed to teach second graders about finding the amount of water with illustrations and calculations.

Students participate in a "thirty-second look," followed by a class discussion about Jan Brueghel's painting "The Entry of the Animals into Noah's Ark". Students then use description words and complete sentences to write about their favorite animal in the painting; draw the animal using line, color, and shape; and present their work to the class.

Teachers can feel overwhelmed when faced with students who are unmotivated to learn. The task becomes less daunting, though, when teachers realize that they can boost student motivation in five important ways: by (1) making positive changes to the learning environment, (2) fostering a sense of community in the classroom, (3) enhancing the interest of classroom activities, (4) responding to individual learning challenges, and (5) building in additional outcomes/pay-offs for learning. Here are some ideas:

This short video and interactive assessment activity is designed to teach fourth graders about finding the total time given a distance between two objects.

An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using any right-angled object, such as a piece of paper. The method uses Thales Theorem to draw two diameters, which intersect at the circle center. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using only a compass and straightedge. The method used involves constructing the perpendicular bisectors of two random chords. The bisectors intersect at the center of the circle. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

This task helps students solidify their understanding of linear functions and push them to be more fluent in their reasoning about slope and y-intercepts. This task has also produced a reasonable starting place for discussing point-slope form of a linear equation.
