Learners explore the concept of factoring trinomials.  In this factoring trinomials lesson, students use the Mack Method to factor trinomials.  Learners watch a video on how to factor a trinomial with a coefficient of 1 with...

Students experiment with scale to solve a problem presented in a video clip. They determine the correct size to use when constructing a model and evaluate the use of proportions in real life applications.

Students combine imagination, block manipulation, and computer applets to investigate fractions.

Students identify the passage of time. They also practice with basic mathematical concepts.

Learners discuss the tourist attractions that are in London. They examine how data can be manipulated by completing a worksheet. They plan a trip to a London attraction after conducting Internet research.

Students examine and analyze the characteristic problem of each phase of the business cycle. Students articulate the appropriate choices for each of the problems described. Students apply the writing process to write an essay.

Second graders participate in a Scavenger Hunt to find out how long 1 cm is. They then find 10 objects that estimate to be 1 cm in length and record their findings on the table provided and check their estimates using a ruler.

Students talk about the types of insects that you might see if you looked in the garden. They then brainstorm for ideas about how to solve the problem, sort objects into categories and display the results and count the objects in a...

Ninth graders identify and describe in their own language, the following 2-dimensional shapes: square, circle, box, pentagon; classify objects by shape attributes. They then list a number of properties that distinguish squares from...

Ninth graders play guess my shape (either describe or use a feely bag to introduce the 3 shapes in the problem.) As they are identified put them in an order as shown in the problem. As the students work on the problem in pairs teacher...

Ninth graders experiment with paper folding to create geometrical shapes. Students analyze the Copymaster of the problem. After the students have worked on their own for a while, stop them and discuss.

Students read the problem and then identify the important information in the problem and highlight. They then brainstorm for ways to solve the problem by drawing a picture and working in pairs.

Students guess the subject of the given problem by reasoning. Then they discuss the ways that the problem could be solved by keeping track of their counting in 10s and showing their work.

First graders investigate the missing numbers on an equation chart in order to practice their addition and subtraction skills. They work with sums up to twenty and use up to twenty objects to work with subtraction equations. They listen...

Students find an object that they estimate weighs 20g and check estimates on the balance scales. They read the problem and work in pairs focusing their understanding on the size of grams.

Pupils discuss the subject of coins and heads and tails. They work in groups to solve Fran's problem concentrating on the fact that the coins are in a row. Any group that finishes early can try the Extension problem.

Pupils state the general rule for a practical situation. They describe a continuing pattern. They use toothpicks to help visualize the problem and answer it correctly.

Students use the properties of multiplication to solve problems. They recall the basic multiplication facts as well as write and solve problems that involve whole numbers.

Students subtract using decimals and find half of a decimal number. They write and solve problems which involve decimals and which require a choice of one or more of the four arithmetic operations.

Students explain face, place and total value of numbers as well as solve three-digit subtraction problems. Before trying answer the problem Students must be able to examine that the same digit is used to represent different amounts.

Third graders use number sense and appropriate problem solving techniques to solve the assigned problems. They write out the solutions to the assigned problems. They work in groups to solve the problem before reporting back to the whole...

Fourth graders are introduced to the problem using a bottle of medicine. They estimate the volume of the medicine and predict the instructions on the bottle. They then think about how they might solve the problem before asking them to...

Fourth graders listen to the problem to the class and think about how they solve the problem and to discuss it with their friends using number sentences in their written record of the solution.

Fourth graders listen to the story of a farmer who only likes to be able to see nine sheet from his window. His wife has brought him another sheep - what now? They work together in pairs to solve the problem and share solutions.
