It's all just a matter of time. The resource provides four Fermi questions in reference to time. The questions are open-ended and require classmates to make use of estimation and dimensional analysis.

Rounding fractions is the focus of a six-question interactive designed to boost concept proficiency. A measured beaker's water level increases and decreases as mathematicians move the tool to represent specific fractions. Questions...

Class members explore the estimation of irrational numbers in association with the Pythagorean Theorem. The first instructional activity of this module challenges pupils to use the Pythagorean Theorem to find unknown side lengths. When...

The 28-page resource contains cards with terms relating to multiplication from inverse operations to front-end estimation to array. Each sheet contains two cards; one with the word and one with the definition.

Youngsters learn the meaning of saving and how to reach savings goals by first reading a story of a young Ugandan girl who is gifted a goat, and then discovering the opportunity costs of savings decisions made by her and her family.

Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...

Put down those calculators! Show scholars they can solve division problems mentally using rounding strategies. They divide four-digit dividends by one-digit divisors, competing 26 problems in all. The first eight have some scaffolding...

Take the resource out of the file cabinet. Young mathematicians estimate the number of sticky notes it would take to cover the surface area of a file cabinet. They answer a set of questions on how the number of sticky notes would change...

What's your favorite pizza topping? Scholars analyze two bar graphs, one depicting a math club's favorite pizza toppings and the other ice cream sales per flavor. As they examine the graphs, learners answer a few comprehension questions....

It is about this big. An assessment provides three questions on the estimations of volume. Pupils determine the quantities needed and use dimensional analysis to arrive at estimations involving dollar bills, paint, and gasoline.

Give a round of applause for completing the task. Scholars watch a video that shows an extremely fast clapper and a timer. The activity requires applying concepts of rates and proportional reasoning to estimate the number of claps in one...

High schoolers begin a discussion on diversity and determine the percent of the population that speak another language at home in the US. Classmates make a prediction of the percentage of people that speak another language at home in...

Use volume to count your change. Pupils watch as a cube is filled with stacks of pennies and make an estimate on how many pennies are in the cube. The teacher provides additional information to the class members about the size of the...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Develop a definition of irrational numbers through an exploration of square roots. The 11th lesson in this series of 25 asks scholars to estimate the value of a square root. Learners observe as the estimation extends further and further...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

A thorough exploration into subtracting multi-digit numbers, this series of lessons is an excellent way to guide learners of any skill level. With a step-by-step lesson plan and straightforward assessment tools, kids are sure to...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Take finding volume of 3-D figures to the next level. In the 22nd lesson of the series, learners find the volume of composite solids. The lesson the asks them to deconstruct the composites into familiar figures and use volume formulas.

Develop a better understanding of the value of pi. Learners explore the area of a circle using estimation and graph paper. While continuing to estimate the area of the circle using smaller and smaller grids, the number pi emerges. 

How can kids use math to learn about marine life? Combine math skills with science lessons in a resource featuring activities about life in the sea. Kids graph and calculate data, solve complex word problems, measure geometric shapes,...

A set of third grade math vocabulary cards include topics that range from addition properties to terms like estimate and fact family. Each sheet has two cards on it. The top half is the word printed in bold text,...

How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project.
