Young mathematicians explore two-digit subtraction. They will investigate multiple ways to subtract numbers involving regrouping. Resources are provided.

Subtracting mixed numbers is easy when the fractions have the same denominator. Here, young mathematicians are prompted to find out how many pounds of peaches are left after Alfredo gives some pounds to his neighbor.

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

Long division without remainders is the name of the game in this resource. Students practice the standard algorithm as they solve problems that containing four- or five-digit dividends and three-digit divisors. There are actually six...

State the population of the state. Pupils research census data on the total population, the number of children their age, and the number of children of the same age and gender in their states. They write these numbers in standard,...

Looking for an out-of-this-world volcanic activity? Geologists study Earth's volcanic history and the neighboring planet Mars by modeling volcanic eruptions, lava flows, and building a shield volcano. Participants use graph paper and...

Relations, and functions, and line tests, oh my! An instructional slideshow demonstrates the definitions of a relation, a function, and the domain and range of a relation. Viewers then learn how to use mappings and vertical...

Use geometry to improve your pool game! Learners analyze the front half of a pool shot to determine its resulting path. By measuring the angle of incidence, they are able to predict the path of the ball. 

It's time for your young artists to shine! Learners examine images to determine possible similarity transformations. They then provide a sequence of transformations that map one image to the next, or give an explanation why it is...

Youngsters participate in three activities using the hundreds chart. They will choose numbers to add up to one hundred. Whoever gets the most combinations wins. Two variations of the game are supplied.

This lesson combines math, visual arts, and language arts activities that all focus on the making, and baling of hay. The activities can be adjusted to address different age ranges. Most of the activities focus on gaining...

Are you looking for a good 3-D geometry instructional activity that includes hands-on activities for your middle schoolers? Look no further than this one! Pupils use centimeter grid paper embedded in the plan, along with detailed...

Help young mathematicians refer to simple addition strategies with a set of math posters. The pages feature ways to remember how to add zero to a number, how to determine if a number is odd or even, and making fast tens.

 A short assessment asks participants to find the original radius required to replace a table top. The problem provides a hypothetical situation of having a segment of a broken glass table top. Pupils find the radius of the...

The shortest distance from point A to point B is a straight line, but measuring distance gets more complicated when there are three points! Given the location of three friends, individuals determine the best point for all three friends...

How many sides does that polygon have? Building directly from lesson number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use Green's...

Students use the internet to research ways to save and earn money. They interview bankers and financial counselors to discover different types of investments. Students create public service announcements to inform their classmates of...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Blow your pupils' minds with information about some of the world's most awesome natural occurrences: volcanos. Class members read a short article and respond to included questions. The focus of the resource is on understanding and...

The lesson starts out with a brain drain, which is a great way to get students to activate prior knowledge and build lasting connections. They tell everything they know about prime factorization, use their knowledge to...

Whoops! Travis accidentally put too much butter into the recipe. Your bakers must find out how to alter the recipe to accommodate different changes by using unit rates and ratios . The activity has multiple parts and calculations with...

We are used to finding the area of a circle by plugging the radius into an equation. Here, learners are required to go further to find multiple areas and calculate the difference. They must detect a pattern in order to figure out the...

Many middle schoolers like to play sports and the equipment that goes with it costs money. The resource sets up an inequality that gives a total amount needed to purchase the equipment and the initial amount of money already obtained. In...
