Using a real-world example, this problem illustrates the thought process that learners need to engage in to understand adding mixed numbers with common denominators. First by looking at estimation, and then by drawing models that...

How do you operate with numbers in scientific notation? The resource provides examples on how to divide and multiply with numbers written in scientific notation. The handout and video also cover the procedure for addition and subtraction...

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...

Third graders use estimation, fractions and decimals to determine the perimeter of objects in the classroom. They are given a worksheet with a list of the items on it. The worksheet has columns beside each of the items for estimation and...

Third graders use whole numbers and fractions to make connections between abstractions of the mathematical world and the real world. For this fractions and measurement lesson, 3rd graders identify, quantify groups , and measure...

Students utilize peanuts to practice fractions.  In this math model lesson, students solve multiplication problems and fractions with real peanuts.  Students use drawing software to graph data from the math equations.

Third graders make models of fractions and mixed numbers. Using fraction strips and drawing pictures, 3rd graders develop conceptual understanding of the equivalent forms. Students use the number line to represent and compare...

Students create packages with a maximum capacity. In this geometry lesson ,students estimate using whole numbers, decimals and fractions. They calculate length, weight and mass of packaging.

Young scholars make a table on the computer, but create fractions and equivalent fractions through the use of color. They are able to manipulate fractions in order to gain a greater understanding of the meaning of whole number that is...

Second graders participate in various activities which help them explain and explain the difference between an estimate and an exact amount.

Fifth graders investigate the interchangeable relationship betweeen fractions and percents. They discuss the concepts using teacher provided questions. Then sutdents work in cooperative groups to maximize scaffolding.

Students examine percents. For this percents lesson, students will estimate percentages. Using advertisements from a newspaper, students problem solve to determine the final price of a sale item.

Seventh graders identify rational and irrational numbers and then, estimate the square root of numbers that are not perfect squares. They then identify what the radical is and differentiate between that and a division symbol clearly....

Students listen to the book, Arthur's Funny Money, then play The Price is Right game to estimate and to chart the price of items to the nearest $1.00 and $10.00. They check their estimates by counting out the actual amount in play money.

Learners estimate, calculate, and count back the amount of change needed from purchases made during small group activities.

Students calculate measurements using different units and fractions. In this algebra lesson, students measure the path that a robot drives. They use a piece of sting to do their measurement and calculate the circumference of the robot's...

Students solve problems with percents, decimals and fractions. In this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

First graders study number pairs and identify number pairs that sum to numbers from 10 to 30. They use number pairs to solve addition and subtraction problems. They make sensible estimates and check the reasonableness of answers.

Students solve for the different ratio and proportion of a problem. In this geometry lesson, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.

Young scholars choose the correct strategy to solve multiplication and division. In this algorithm lesson, students use at least two strategies that use properties of operations and estimation. Young scholars also recognize the...

Learners multiply decimals and/or mixed numbers. They explore the effects of multiplying decimals and mixed numbers. They practice estimating answers when a number is multiplied by a decimal or mixed number.

In this mathematics worksheet, students solve various word problems by selecting the correct fraction for each response. There are eight problems to solve on the sheet.

Students explore mathematics by participating in a group activity. In this number value lesson plan, students identify the uses for decimals and how to best estimate whole numbers based on decimals and fractions. Students collaborate...

Sixth graders conduct a survey and collect data to construct a bar graph that will then be changed into a circle graph. With the bar graph, 6th graders compare estimated fractions and percentages and estimate percentages. With the circle...
