Who has the most? Young learners practice charting data using familiar information. They help fill out a classroom chart by recording the number of people, pets, televisions, etc. in their home. Guiding questions help them investigate...

Apply the concept of magnitude to estimate values and compare numbers. The ninth lesson of the 15-part series asks learners to write numbers to their next greatest power of 10 and then make comparisons. Scholars begin to understand the...

Estimate and explore the length and weight of classroom items using standard measurement and scales. Young scholars will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data...

Lead the class in a review of the basic concepts and procedures involved in measuring length, weight, and volume. After whole group instruction, small groups and individuals practice measuring by completing a variety of fun activities...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Students find patterns relating the lengths of the sides of squares to their areas. In this squares and square roots lesson, students draw squares and find their areas. They estimate the sides of square when given the area. Students use...

Tell the story of the math. Given a graph of a linear system, learners write a story that models the graph before crafting the corresponding functions. Graphs intersect at an estimated point, allowing for different variations in the...

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...
