Just how far will the Facebook post go? Lead a discussion on how to manipulate the sum of a geometric series to figure out a formula to find the sum at any step. The plan contains an alternative to the discussion with more...

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....

What percent of the mixture is juice? Pairs use their knowledge of proportions to determine what percent a mixture is juice given the percent of juice in the components. Pupils use the procedure learned with the juice mixture problem to...

Middle and high schoolers research the life of Pythagoras and the Pythagorean theorem. They write a short biography of Pythagoras and learn to apply the theorem in their study of right triangles.

Create your own adventure story ... well, not really. The fifth lesson in a 21-part series has pairs create story contexts for division problems. The lesson presents a step-by-step process for pupils to follow in writing such stories.

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.

Students use paper cups and colored chips to observe properties of operations with real numbers. As a class, students brainstorm and use manipulatives to demonstrate associative, commutative, distributive identity and inverse properties....

Your second graders explore two digit addition with regrouping. They will investigate problem solving strategies within the context of a trip to the zoo. Multiple resources and assessments are provided.

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

What other inventions was Thomas Edison responsible for besides the telegraph and lightbulb? Incorporate a set of worksheets into your study of Edison and other inventors. The 48-page packet includes all types of activities from word...

Manipulatives make learning division easier! Your class will discover the difference between dividing with one- and two-digit divisors, and practice the procedures for each using the standard algorithm. They will use estimation to ensure...

Sometimes the solution is all a matter of perspective. The short assessment task presents a problem to pupils that requires them to make sense of a diagram. Once learners see two similar triangles, the rest of the solution is solving a...

Develop a sense of normal. Learners develop two questions to ask classmates to gather numerical data before creating a box and whisker plot and a histogram to display their data. Class members make inferences and investigate the data...

Fourth graders examine the relationship between multiplication and division and subtraction and division, and determine which operation is needed to solve various problems. They observe and participate in a teacher-led lecture, and...

Young scholars discover how they can use manipulatives to solve word problems. In this problem solving lesson, students read Raul's Apples Problem and then complete a worksheet, using beans or counters to solve the problem. Young...
