Students build a scaled model of the solar system. In this space science activity, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

Young mathematicians solve linear equations by drawing models of algebra tiles using colored pencils. To finish, they solve the same equations algebraically and check their answers using a graphing calculator.

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

Learners study what occurs in the division process, rather than just following prescribed steps. They expand number sense to include integers and perform operations with whole numbers, simple fractions, and decimals. They write a word...

Students use Cuisenaire rods to explore common denominators. In this fractions lesson, students build Cuisenaire representations of fractions, then find their equivalent counterparts to find the common denominator.

Examine food labels to determine percentage of fat and sugar to total calories with middle schoolers. Daily nutritional guidelines are discussed and learners will decide how well their foods fit into a healthy diet. In the provided...

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

Students use optimization concepts to design their own container. In this optimization lesson plan, students understand how the optimization concept is critical in calculus and why products are packaged the way they are.

Use a vocabulary chart to introduce math functions. The class defines a list of mathematical vocabulary terms on a worksheet, as well as completes equations and expressions. They examine word problems and practice transcribing them into...

Factor in different strategies in a lesson for factoring quadratics. Young mathematicians first create tables and area models to factor quadratic trinomials into two binomials by guess and check. Learners then investigate how they can...

Discover the connection between vectors and translations. Through the instructional activity, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then...

Factor in this resource when teaching how to factor polynomials. Scholars use algebra tiles to factor linear and quadratic expressions. They practice their skill by working on example problems from a worksheet.

Tenth graders create polynomial quilts. In this polynomials lesson plan, 10th graders use concrete models, such as construction paper, to create various shapes described. Students use the FOIL method to multiply terms and to get a square...

In this Christmas animal math worksheet, learners solve 36 single and double-digit addition problems and then follow the coloring key and color in each sum a different color.

Students use manipulatives to explain the concept of dividing multi-digit numbers.

Third graders review and practice strategies for solving division problems. In this division by 3's lesson, 3rd graders play games, use an interactive whiteboard, create flashcards, and solve word problems. 

Second graders convert fractions to percentages.  In this interactive whiteboard percentages lesson, 2nd graders problem solve using percentages, fractions, and decimals.

Ninth graders discuss the real number system and its' properties. In this algebra activity, 9th graders discuss rational, irrational, closure, real numbers and the distributive property of algebra. They solve problems using these...

Fifth graders practice solving word problems using highlighted strategies. In this word problem lesson, 5th graders brainstorm and  use words as clues that indicate the math operations that will be used to solve problems. They use...

Students complete fraction word problems using TI-Explorer Calculators.

Students practice multiplying decimals and/or mixed numbers, explore the effects of multiplying decimals and mixed numbers, and practice predicting the effects of multiplying a number by a decimal or mixed number.

Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.

Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...
