Students determine how many number cards are needed to display the dates of the month. In this place value notation lesson plan, students write numbers on blank cards to see how many are needed of each number to makes all the...

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Students explore the concept of modular arithmetic and cryptography. For this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Sixth graders represent division of fractions using manipulatives, such as freezer pops, candy bars, and models such as drawings squares. They develop an algorithm from these examples and solve problems using fractions.

Second graders accurately measure the distances they and their classmates jump. They determine the mean, median and mode of specific jumps. They are required to have two measurements for each classmate, one for standing long jump and one...

Second graders explore the inverse relationship of addition and subtraction in a "hands-on" activity based on the fact families of ones, twos and threes.

Fourth graders complete a worksheet that asks them to order operations within a mathematical expression. students evaluate the expressions in the correct order using mental math and paper. The results are recorded on the worksheet.

Students play a team subtraction game, subtracting two-digit numbers and using addition to check their subtraction. They solve subtraction problems at the board while the team solves the same problem in their seats.

Students calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.

Students observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.

Students 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.

High schoolers practice solving quadratic equations using a form called Complete the Square.

Students view examples of a ray, opposite rays, collinear rays, angles, and straight angles. They discuss and demonstrate how to use a protractor and complete worksheet problems on rays and angles.

Students examine how a Richter scale operates. They create a booklet illustrating each rating on the scale. They discover how engineers use different measurement tools.

Fourth graders examine the attraction between two different charges to investigate lightning in a thunderstorm. They complete an experiment and a worksheet.

Students investigate geometric shapes through volume and dimensions. For this geometry lesson, students measure, weigh, and calculate sizes and volume based on estimation and calculation. They review important vocabulary related to...

Seventh graders explore the order of operations. They compare how the values of equations change when the order of operations is not followed. They discuss the order of operations. Independently, 7th graders solve equations. Students...

In this multi-step problems worksheet, 4th graders read and analyze the paragraph on the worksheet about types of tools in order to answer four math questions with multiple choice answers.

Students participate in an online computation game. In this computation activity, students practice simple computations and use an internet site to review addition and subtraction facts.

In this geometry worksheet, students calculate the areas of rectangles. They use the formula for area of a rectangle.

Multiplying each number by three serves as a warm-up on this division task. The remainder of the worksheet provides 28 division problems, each with a divisor of three. Ideal for an assessment, especially because the answer key is readily...

First notice that an answer key is available by the click of a box at the top of the page. Then you will see that learners practice the  four times table before delving into division. Twenty-eight quotient-finding problems follow. A...

Twenty-four problems fit neatly on this division worksheet. For each, youngsters must divide a three-digit number by a single digit. There will be remainders in all of the problems, so make sure not to assign it until you have thoroughly...
