Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!

Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying algebraic expressions. Use the game screen to test your multiplication and factoring skills!

Engaging in games played around the world, students will learn about other cultures.

This lesson is about the estimation of the value of Pi. Based on previous knowledge, the students try to estimate Pi value using different methods, such as: direct physical measurements; a geometric probability model; and computer technology. This lesson is designed to stimulate the learning interests of students, to enrich their experience of solving practical problems, and to develop their critical thinking ability. To understand this lesson, students should have some mathematic knowledge about circles, coordinate systems, and geometric probability. They may also need to know something about Excel. To estimate Pi value by direct physical measurements, the students can use any round or cylindrical shaped objects around them, such as round cups or water bottles. When estimating Pi value by a geometric probability model, a dartboard and darts should be prepared before the class. You can also use other games to substitute the dart throwing game. For example, you can throw marbles to the target drawn on the floor. This lesson is about 45-50 minutes. If the students know little about Excel, the teacher may need one more lesson to explain and demonstrate how to use the computer to estimate Pi value. Downloadable from the website is a video demonstration about how to use Excel for estimating Pi.

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?

Build coin expressions, then exchange them for variable expressions. Simplify and evaluate expressions until you are ready to test your understanding of equivalent expressions in the game!

In this version of a Sumo wrestling bout, players use mathematical skills to move their opponent's counter beyond the track and "out of the ring." Learners reveal playing cards and the player with the large value card pushes their counter a number of spaces equal to the difference between the two card values multiplied by the lower of the two card values. Learners can also explore what happens when a zero card is added to the mix.

In this Adaptation Name Game, students sitting or standing in a circle play a version of tag, with one person in the center. When a person in the circle says another person’s name, the person in the center of the circle tries to touch the person whose name was said, before they can say someone else’s name. Later, students pause to brainstorm strategies to improve their performance, then play some more. Students learn that this was a representation of how certain structures and behaviors help organisms survive in their habitat, and that these are adaptations that species inherit over time. This game helps students learn each other’s names, while “lightly” introducing them to what adaptations are. Note: This activity is only an introduction; to gain any meaningful understanding of the topic, students will need more adaptation-focused activities, such as Adaptations Intro-Live!, Structures & Behaviors, and Related & Different, which engage students more deeply in understanding the concept through interactions with real organisms.
