New ReviewEstimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

New ReviewNine true or false, multiple-choice, and discussion questions make up an interactive designed to reinforce scholars' knowledge of prime and composite numbers. A number chart reveals every prime number through 100. 

New ReviewThere's got to be a better way. Scholars learn that the distributive property does work with subtraction and not just addition. Using that fact, the video shows how to find the product of two numbers by rewriting a complicated number as...

New ReviewWho pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

New ReviewBag the sweet resource for later use! Pupils learn about engineering design by developing a new, improved bag for candy from thin plastic sheets or from paper. The bags are to be visually appealing, but should also be functional. To...

New ReviewHere's a resource teachers won't want to wash their hands of. Given a task where a full bar of soap is on one side of a balance and 3/4 of a bar of soup and a 3/4-ounce weight is on the other side, young mathematicians must determine the...

New ReviewCould you develop your own way to add fractions with unlike denominators? An in-depth task has scholars examine a fictional conversation between several people in which they discuss a method of adding fractions with unlike denominators....

New ReviewIf the fractions don't have a common denominator, make them have one. Learners first read and analyze a conversation of pupils trying to add 2/5 and 1/2. They compare the process of adding fractions to the process of adding quantities...

New ReviewMultiplying fractions doesn't need to be a mystery. An interesting task has scholars question why the standard algorithm for multiplying fractions works for all fractions. It requires them to read a conversation about a solution method...

New ReviewThree heads are better than one. After reading a conversation between three friends about how to compare fractions, scholars analyze and discuss each presented strategy. These include using unit fractions, using benchmark fractions,...

New ReviewCatch me if you can. Scholars collect data on reaction time by catching a falling ruler or by using an Internet app. They determine the median of the data, create graphs, and analyze the results. They also compare their data to the rest...

New ReviewDoes lemonade taste better when yellow? A tasty experiment has scholars determine the answer to the question. It requires conducting a taste test with lemonades of different colors (from food coloring), and then collecting and analyzing...

New ReviewEveryone's a winner. Scholars analyze a spinner with five unequal sections, three of which represent winning a toy car and the other two represent winning a toy truck. They conduct an experiment to estimate the number of toy cars and...

New ReviewSpin to win a toy car. A fun activity has pupils use a spinner in which three of the equal sections represent winning a toy car, and the fourth section represents no car. They record the number of wins after certain numbers of spins,...

New ReviewAim high with a task on window washers. An assessment task challenges learners to determine the number of windows two people wash. They do this using a given number of window rows on each side of a building. In addition, they find the...

New ReviewPaste this resource into your lesson plans like you'd paste a tile onto a mural. Given a diagram of a tile mural with rectilinear figures, future artists determine the perimeters and areas of the figures. They must then develop their own...

New ReviewHere's an assessment task that's better than watching a show. Young mathematicians solve word problems involving multiplication and division with equal groups. They must find the total number of attendees on a trip to a theater based on...
