Buying on Credit
Explore using credit in this financial responsibility and math lesson. Learn to identify the acronym of "PRT" as Principle x Rate x Time, then calculate interest based on this formula. Do some real-world problem solving and choose...
Illustrative Mathematics
“Crossing the Decade” Concentration
Young mathematicians concentrate on learning to fluently count. Following the rules of the classic game Memory, children take turns flipping over cards in order to find pairs of numbers that cross a decade (e.g. 29 and 30). For younger...
CCSS Math Activities
Gym
Math requires strength training, too. Scholars consider three different pricing systems for a gym. Given several scenarios, they determine which gym would be cheaper and find how many visits it takes for the costs to be equal.

Shape Sequence Search
Learning that size and orientation don't affect the classification of shapes is a big step for young mathematicians. Support children with developing this key understanding by looking at the array of shapes included in this resource. For...
Balanced Assessment
Frosting on the Cake
Party planners need algebra too! Here, pupils decide the perfect size of a cake based on available ingredients. They use the concepts of area and perimeter to make their conclusions.
PBL Pathways
Solar Toasters
Help a company maximize their profits! A detailed project-based learning activity examines two production scenarios. Your young scholars write a linear demand function. They then apply the function to develop a revenue, cost, and profit...
