Ever wonder how many marshmallows long your toothbrush is? Well, you're in luck! This hands-on measurement activity requires young mathematicians to determine the length of their toothbrush using Unifix® cubes, buttons, Cheerios, bear...

How many unifix cubes tall are you? If you're not sure, then perform this math activity with your class and find out. Working in pairs, young mathematicians make measuring sticks out of unifix cubes in order to determine the length of...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-instructional activity series supports children with learning how to measure the area of squares,...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

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...

Expand the the comparative language of young mathematicians with a hand-on weight measurement activity. Working independently or in pairs, children compare the weight of large wooden blocks to various other classroom objects, recording...

Break out the balances for this primary grade lesson plan on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

Swimming is more fun with quantities. The short assessment task encompasses finding the volume of a trapezoidal prism using an understanding of quantities. Individuals make a connection to the rate of which the pool is filled with a...

Stop the summer lag with a set of second grade Common Core based math practice sheets. Learners fill in hundreds charts with missing numbers up to 1,000. They practice writing numbers in standard, expanded, and word form. Children also...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

I like algebra, but graphing is where I draw the line! Worksheet includes three multiple-part questions on interpreting and drawing line graphs. It focuses on the abstract where neither axis has numbers written in, though both are...

Every movement in the world can be measured and even motionless objects can be significant indicators of movement. Focus on motion graphs that feature distance vs. time, speed vs. time, and positive and negative acceleration.

Fresh off the press, these math newsletters will challenge the problem solving skills of your young mathematicians. With an incredibly wide variety of questions covering the topics of arithmetic and geometry, these unique...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...
