Without measuring, can estimators determine which string is the longest? The shortest? There are two sets of strings here for learners to evaluate, circling the shortest in the first set and the longest in the second. Next, they eyeball...

This is great go-to activity for those spring or fall days when the weather beckons your geometry class outside. Learners start with a small tree, devising strategies to accurately estimate the leaf count. They must then tackle the...

Celebrate fall with four pumpkin themed hands-on activities! After learning about pumpkins, scholars complete two activity sheets that reinforce estimation and word problems. They then plant pumpkin seeds and bake a pie in...

Using clocks as dining tables? Scholars estimate the number of people that can sit around the face of the clock on the Royal Liver Building in Liverpool. They use estimation to justify their responses.

Clarify the Common Core standards for your eighth grade mathematicians with this series of classroom displays. By rewriting each standard as an achievable "I can" statement, these posters give students clear goals to work toward...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

Through estimating, scholars are able to make these word problems simpler as they multiply to find approximate answers. Using an example as guidance, they solve five scenarios, each of which has space for learners to show their work. The...

Shoot and score with three basketball-themed lessons about decimals. Young mathematicians compare game statistics, make trash can hoops, and play a data spinner game to practice identifying digits and values within decimal numbers.

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....
