Odd or even—fifty-fifty chance? Pupils first conduct an experiment rolling a pair of dice to generate data in a probability lesson. It goes on to introduce mutually exclusive and non-mutually exclusive events, and how to use the...

High schoolers observe and solve examples of the complementary angle theorem. They complete the How Do You Pay a Complement to an Angle worksheet, and write a response in their math journal.

Establish 1:1 correspondence by counting students, first one gender, then the other. Give each child a colored cube (one color for boys, another for girls) and have small groups determine more or less and how many all together. As a...

Discover trigonometric ratios that complement each other. Using two videos, the activity introduces the trigonometric ratios. The class discovers the relationship between the sine and cosine of complementary angles.

Young scholars identify the probability of an event occurring. Learners explore the complement of an event in finding why an event will not happen. They also explore basics of probability within algebra.

Ease children's back-to-school jitters with this primary grade instructional activity based on the book The Kissing Hand by Ruth E. Harper. Starting off with a singing of the song "I Wish I Had a Little Red Box", children go on...

What are the advantages and disadvantages of using a credit card versus a debit card? What are the costs of using a debit card irresponsibly? Here you'll find a instructional activity on key concepts that every learner...

Students create a hands-on graph then complement this by making a computerized version of the same graph using Graph Club. They read various graphs, so as to be more prepared for state exams which require this concept.

Ninth graders investigate the concept of probability. They use a clear objective that is a visual cue for what is required for the lesson. They apply the basic practices of probability to real life like situations.

Seventh graders use educational software in order to practice lesson objectives. They define rate and ratio. Students solve distance problems given two variables. They also use a problem solving strategy that can be defended in its usage.

Fifth and sixth graders engage in a series of activities which show them the importance of using different types of measurement strategies. One of the primary goals of the instructional activity is to show learners that measurement is...

Students identify angles.  In this angles that pair lesson, students identify adjacent, vertical, complementary, and supplementary angles.  They use straws, pretzel sticks to demonstrate given types of angles. 

Learners create puzzles of animals based on the 12-animals cycle of the Lunar Calendar. They use logical or spatial relationship skills. Students comprehend the mathematical term geometry. They research the history, beliefs of the...

Eleventh graders investigate the way credit cards work when collecting interest. In this algebra lesson plan, 11th graders investigate the growth of interest exponentially when using a credit card. They calculate what the cheapest rate...

Second graders, in groups, estimate amounts in various jars. They sort each jar from least to greatest amount.

Students, after making quantitative and qualitative observations of their rocks, construct a Venn diagram or dichotomous key to classify their rocks.

Students complete their examination over the Jewish Diaspora. Using population figures, they discover the importance of percentages in exploring trends. They use their own ethnic group and determine how it is represented in the United...

Learners review and analyze graphs and tables as a group. They develop their graph and data analysis skills by converting data tables from Human Activity and the Environment into graphs.

Students listen to story Two of Everything, illustrate coins they would put into the Magic Pot using paper and pencil, and solve Magic Pot riddles by viewing slide show and predicting coin totals. Students then create table listing...

The objective of this site is to actively involve students via software simulations so that the determination of the sinusoidal model has a geometric flavor that complements the algebraic tools stressed in texts. This approach also...
