This short video and interactive assessment activity is designed to teach second graders about counting cubes and creating a place value diagram.
Students who work on this task will benefit in seeing that given a quantity, there is often more than one way to represent it, which is a precursor to understanding the concept of equivalent expressions.
This is an instructional task related to deepening place-value concepts. The important piece of knowledge upon which students need to draw is that 10 tens is 1 hundred.

This short video and interactive assessment activity is designed to teach second graders about decomposing decimals into place values to tenths.
This short video and interactive assessment activity is designed to teach fifth graders about one-step conversions between hundreds, tens, and ones.
This short video and interactive assessment activity is designed to teach fourth graders about completing the expanded forms of numbers (place values to 1,000).
This short video and interactive assessment activity is designed to teach second graders about identifying digit values in numbers (numbers to 10,000).
How can an understanding of pH—a logarithmic scale used to identify the acidity or basicity of a water-based solution—be used to design and create a color-changing paint? This activity provides students the opportunity to extract dyes from natural products and test dyes for acids or bases as teams develop a prototype “paint” that is eventually applied to help with a wall redesign at a local children’s hospital. Students learn about how dyes are extracted from organic material and use the engineering design process to test dyes using a variety of indicators to achieve the right color for their prototype. Students iterate on their dyes and use ratios and proportions to calculate the amount of dye needed to successfully complete their painting project.
