Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Students calculate unit rates with fractions and whole numbers. In this algebra lesson plan, students compare numbers, perform long division, and calculate the rate of different units through conversions. They model some of the problems...

Find the faster rate. The resource tasks the class to compare proportional relationships represented in different ways. Pupils find the slope of the proportional relationships to determine the constant rates. They then analyze the...

Bear with your classes as they explore unit rate and proportions using gummies! Gummy bears come in many different sizes, including a 2,250-gram super bear! The task asks learners to determine how many regular bears and how many mini...

You literally need to use the resource. Young mathematicians solve geometric problems by using literal equations. They go on to solve distance/rate/time problems by using literal equations — a great progression that helps introduce the...
