Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

Emerging engineers perform pre-lab calculations in this first of a three-part lesson on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of their...

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

Quickly get to the decimal point. The last assessment in a nine-part series requires scholars to work with decimals. Pupils compare the race times of several athletes and calculate how much they have improved over time. During the second...

Comparing the movement of graphs geometrically when small changes are made to the parent function motivates this collaborative discussion on the transformations of functions to their various forms. Vertical and horizontal shifts due to...

Here is an adding and subtracting decimal hundredths worksheet in which learners add and subtract numbers that have decimals in the hundredths. They complete 32 problems where everyone adds and subtracts numbers that have decimals in the...

Students explore number sense by creating a math presentation in class. In this parts of a whole lesson, students define and discuss the relationship between fractions, decimals and percentages before completing a problem worksheet in...

Teach collaboration and communication skills in addition to graphing logarithmic functions. Scholars in different groups graph different logarithmic functions by hand using provided coordinate points. These graphs provide the basis for...

Upper graders solve problems involving measurement of squares and rectangles to practice multiplication skills, finding area, and calculating prices and percentages. A performance assessment is included.

Third graders tally, sort, and organize pizza orders from monthly school sales. They create an advertising campaign to promote the School Pizza Sale, record the data in graph form, compare and contrast the tallies throughout the year,...

Which one has two more? Each row of objects has a corresponding row, and mathematicians determine which one has two more than the other, checking it off. They work with single-digit values here and should be encouraged to write the...

Each of these sets of buttons has a corresponding set with four more. Learners examine pairs to determine which one has four more, checking it off. Consider also asking them to write down the specific number of each set to encourage...

Skip count along the mushrooms to complete these number sentences which give young scholars an introductory look at addition and subtraction. Starting from five double-digit numbers, they subtract or add by threes, fours, and fives to...

Students become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.

Here is an extensive set of teacher's notes to help you teach all about integers. Begin by introducing a number line and how it can be used to visualize positive and negative numbers. Talk about absolute value and the additive inverse...

Sit back, relax, and transport to 1787! This lesson on the Constitution begins with guided imagery of the Constitutional Convention. The class reads A More Perfect Union: The Story of Our Constitution in an...

The equations look different, but their graphs are the same. How can that be? This activity leads your mathematicians in an exploration of three different forms of the same quadratic function. After comparing the equations, their graphs,...

Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...

Probability, especially conditional probability, can be a slippery concept for young statisticians.  Statements that seem self-evident on the surface often require a daunting amount of calculations to explicate, or turn out to be...

Mo' money, mo' problems! But don't worry, here is an assessment that proves to young mathematicians that they can solve actual money problems. The resource includes 11 money problems involving addition, subtraction, multiplication,...

Reinforce estimation and the four operations—addition, subtraction, multiplication, and division—with eight page, 15 problem independent practice exercise.

Have your class design their own mathematical study aids. Learners collaborate in groups on the design of tri-fold presentation describing the relationships between mathematical computations. Then, they write a business letter to the...

Students explore math facts.  In this calculation and math facts lesson, students play a board game in which addition, subtraction, multiplication, and division math facts are practiced.  A copy of the game is included.

Fifth graders estimate their results and then prove through calculations. For this math lesson, 5th graders solve problems using multiplication, division, addition, and subtraction. They also use mental math to solve their problems.
