Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson plan in a seven-part series.

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

Second graders explore number values by completing estimation problems in class. In this place value lesson plan, 2nd graders identify the use of decimals in numbers and how they relate to fractions or parts of a whole. Students utilize...

Learners use percents to solve problems, see math in the real world, and make reasonable choices pertaining to percents.

Seventh graders practice using pattern blocks. In this pre-algebra lesson, 7th graders complete tasks that require them to compare fractions, make fractions equivalent, and add fractions.

Fourth graders use manipulatives to practice math patterns.

Six shamrocks show off several single-digit numbers for lucky little leprechauns to analyze. Beneath each shamrock are four lines on which learners write the numbers in order from least to greatest. Give your class practice comparing and...

Students discover the advantage of estimation over simple guessing using number relationships. They also discover how useful a mathematical tool estimation is in everyday life.

For this subtracting two- and three-digit numbers worksheet, young scholars, with a partner, problem solve and calculate the answers to fourteen subtraction equations.

Students convert among liquid measurement units. In this measurement lesson, students use Visual Thesaurus to gather information about customary units for liquid measure such as cup, pint, and quart, then students practice converting...

In this counting skills worksheet, learners solve 10 multiple choice math problems regarding most and least. Students may view the correct answers

Students demonstrate how to count by 2's. In this number sense lesson, students review skip counting on the hundreds chart and recognize the pattern of counting by 2's. Students use a reproducible of a calendar to color in the days as...

Seventh graders investigate the mathematical concept using a lecture format. The instructional activity includes a classroom management section with suggestions for instructional activity execution. Students write a definition for the...

Students investigate the patterns of different data sets of numbers. They use critical thinking skills in order to find the missing numbers in any given set. This lesson helps to develop the skill of number sense.

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

It's a balancing act! Pupils balance pennies on a ruler to create a physical representation of a dot plot. The scholars then find the distances of the data points from the balance point, the mean.

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Does the symmetry and transitive property apply to similarity? The 10th segment in a series of 16 presents the class with a group of explorations. The explorations have pairs show that similarity is both symmetrical and transitive....
