Pupils play "Fraction Line Up," a game to compare fractions with unlike denominators with the use of a deck of cards. After the game, each player explains one of the strategies that was helpful to him/her during the game. In explaining,...

Teach solving for unknowns through a problem-solving approach. The grouping of five lessons progresses from finding an unknown through simple reasoning to solving simultaneous equations involving three and four variables. Each lesson...

Examine the consequences of varying speed.  An engaging set of five problem sets challenges young mathematicians by targeting a different grade level from K-12. In the initial lesson, scholars make conclusions about the time it...

Young scholars notice a number pattern in the book The Rabbit Problem by Emily Gravett. In this number pattern instructional activity, students represent and describe numbers appropriate to their grade level.

Create number sentences and equations to solve geometric problems. Each activity in the series of five asks young mathematicians to consider different-sized tiles to build structures according to specific criteria. The first activities,...

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

Students use mental strategies to work out the difference between 2 two-digit numbers where the answer is less than ten. They write and solve difference problems where one number is a two-digit number and the other is a single digit...

Students use a dictionary to gather appropriate information for writing simple definitions. They recognize prefixes that relate to numbers, such as mono-, bi-, and tri-. Pupils use their creative abilities to extrapolate new words to...

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Students explore the concept of problem solving strategies. In this problem solving strategies lesson, students discuss methods for solving problems such as re-reading a problem, stating the facts, drawing a picture and so on. Students...

Elementary and middle schoolers identify different units of liquid measurement. They use the online Visual Thesaurus to learn about the relationships between units of liquid measurement.

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....

Students use an Internet tool, "The Take-Away Bar" to solve subtraction problems by breaking them into parts. They write and solve comparison problems. Students make sensible estimates and check the reasonableness of answers. They use...

Now that the practice is over, see if young mathematicians can utilize their new skills on finding common denominators and adding fractions. The assessment contains one map challenge and follows with skills practice. 

The learner puts reasoning and estimation to work. The directions are to place a decimal in the answer to make the equation true. Pupils are to look at the two problems, one multiplication and one division, and estimate an answer. No...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Exactly how fair are the board games children grow up playing? Young mathematicians investigate this questions as they work their way through this five-lesson series on basic probability. 

Students explore number sense by participating in a class fraction game. In this number value lesson, students utilize strips of paper with fractions written on them and conduct a trivia game in which teams challenge each other. Students...

Pupils use the problem solving strategy of guess and check to investigate math word problems. They determine which problem solving strategy or strategies would work best in problem situations.

Using the concept of a candy vending machine, young mathematicians explore the sugar ratios found in different types of candy. Using the provided information, class members calculate and compare different ratios in...

Help your class make sense of quantities and their relationships. Given is the product of two numbers. It is up to your number crunchers to think about the quantitative relationship when the product is one-tenth or ten times the product...

A resource that makes for excellent group work as learners explore the area and perimeter of different complex designs made up of squares and circles. The commentary gives a clear definition of perimeter, but suggests that group members...

Develop young mathematicians' ability to compare fractions with investigation into the number 1/2. After brainstorming a list of fractions equivalent to 1/2, children identify a pattern in the numerators and...

What makes a good sample? Your classes collaborate to answer this question through a task involving areas of rectangles. Given a set of 100 rectangles, they sample a set of five rectangles to estimate the average area of the figures. The...
