Explore vocabulary and notation related to triangles and congruence. The fifth lesson in the 29-part series helps pupils build their knowledge of triangle relationships. Individuals identify corresponding parts of identical triangles and...

Using patty paper, classes determine that only one triangle is possible when given two specific angle measures and a side length. As the 10th instructional activity in the series of 29, young math scholars add these criteria to those...

Teach the connection between area models and the distributive property through problem-solving. The 22nd activity in a series of 29 explains the distributive property graphically. Learners build area models from word problems and convert...

Equivalent ratios show up on tape. Young mathematicians use tape diagrams to create equivalent ratios in the initial lesson on the topic. They learn the definition of equivalent ratios and use it to build others in the third segment of a...

Make math much simpler with mental math methods. The 16th installment in a series of 21 looks at ways scholars can apply mental math to convert division problems into easier problems with the same quotient. Multiplying or dividing both...

Who knew the sum of a number's digits gives such interesting information? The 18th installment of a 21-part module has scholars investigate division by three and nine. After looking at several examples, they develop divisibility tests...

Scholars learn to order rational numbers in the seventh lesson in a series of 21. Reasoning about numbers on a number line allows for this ordering.

Statements often have multiple interpretations — but not these inequality statements. Scholars compare rational numbers and write inequality statements symbolically. The lesson includes problems that require comparing three numbers.

Positive and negative numbers are all around us. Groups read short story contexts and identify a rational number that represents the values in the context. They order the rational numbers and interpret statements of inequality.

Scholars learn to plot points on the coordinate plane. The lesson introduces the idea that the first coordinate of a coordinate pair represents the horizontal distance and the second coordinate represents the vertical distance. 

Multiple meaning words is the focus of a lesson designed to reinforce the use of context clues. Scholars listen carefully to a variety of sentences using the words pool and cast to decide which definition best fits the...

Sometimes the best view is from the farthest distance. Satellite imaging makes it possible to create altitude maps from far above the earth. A three-part activity has your young scientists play the role of the satellite and then use...

Powered up! Here's a great resource on exponents. Scholars build on their previous understanding of exponents to include all positive real number bases. Distinguishing between an and a^n is a major goal in the fifth lesson of a 36-part...

Bring your young mathematicians into the fold. Scholars conduct an activity folding paper to see the relationship between the number of folds and the number of resulting layers in the 23rd installment of a 36-part module. The results of...

Find the point that splits the data. The lesson presents to scholars the definition of the median through a teacher-led discussion. The pupils use data lists and dot plots to determine the median in sets with even and odd number of data...

Which graph belongs to which summary statistics? Class members build upon their knowledge of data displays and numerical summaries to connect the two. Pupils make connections between different graphical displays of the same data in...

A discussion of bioluminescence launches an investigation of animal adaptations. After re-watching the opening minutes of Dark Water, class members listen to a reading of What Do You Do with a Tail Like This, and then create a new...

After watching the documentary Dark Water about a traditional Chumash ceremony and reading a Chumash origin story, viewers are asked to create a coat of arms and to craft an essay that details a family tradition or their own origin story.

After viewing The Last Roundup, a documentary that examines the transitioning of Santa Rosa from a privately owned island to a National Park, class members adopt the point of view of Tim Vail, a member of the family that once owned the...

Small groups create skits that illustrate the different perspectives of those involved in the transitioning of Santa Rose island from private ownership to National Park.

After viewing the West of the West's documentary Cache, individuals craft either a newspaper article chronicling the discovery of the cache on San Nicolas Island, a historical narrative of the placement of the cache in the cliff side, or...

After watching West of the West's documentary The Lone Woman of San Nicolas Island, class members imagine how Juana Maria/Karana may have felt about living alone on the island for 18 years and craft a blackout poem or a narrative in...

Rate ratios with unit rates and rate units. Pupils take ratios and determine their associated rates and unit rates. The scholars identify the different aspects of rates, the unit rate, and the rate unit. The lesson is the 16th in a...

After watching West of the West's documentary on Catalina Island, The Magic Isle, class members research how Walt Disney's and William Wrigley's different visions impacted the island.
