This lesson is about trying to get students to make connections between ideas about equations, inequalities, and expressions. The lesson is designed to give students opportunities to use mathematical vocabulary for a purpose to describe, discuss, and work with these symbol strings.The idea is for students to start gathering global information by looking at the whole number string rather than thinking only about individual procedures or steps. Hopefully students will begin to see the symbol strings as mathematical objects with their own unique set of attributes. (7th Grade Math)
This lesson is based on the results of a performance task in which we realized that studentsŐ understanding of area and perimeter was mostly procedural. Therefore the purpose of this re-engagement lesson was to address student misconceptions and deepen student understanding of area and perimeter. The standards addressed in this lesson involve finding perimeter and area of various shapes, finding the perimeter when given a fixed area, and using a formula in a practical context. Challenges for our students included decoding the language in the problem and proving their thinking. (7th Grade Math)
Task Description: This task allows students to demonstrate their understanding of place value. Throughout the task they are required to use operations to solve problems, understand and apply properties of numbers, and compose and decompose numbers in flexible ways. This packet contains a curriculum-embedded CCLS aligned task and instructional supports. The task is embedded in a 2-3 week unit on Number and Operations in Base 10. The mathematics of the unit involves understanding the meaning of base ten and using that understanding to solve number and real life problems. Students will use a variety of tools to help articulate understanding of base ten and to solve problems using addition and subtraction of numbers less than 10, less than 20 and on to less than 100.
The foundation of this lesson is constructing, communicating, and evaluating student-generated tables while making comparisons between three different financial plans. Students are given three different DVD rental plans and asked to analyze each one to see if they could determine when the 3 different DVD plans cost the same amount of money, if ever.

In Counting on Art, students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts.In Pippin's Story, young children (grades K–3) focus on a painting by African American artist Horace Pippin. They will learn how to "read" the clues in a painting and write a story about the work. Students will also solve counting and time problems and create their own "secret number" painting.Calder's Balancing Acts focuses on math in the mobiles of Alexander Calder. Elementary- level students (grades 2–5) will learn about the artist and write equations based on Calder's art. Upper-level students (grades 6–8) will discover patterns and the Fibonacci sequence. Both levels will make their own math mobiles.Cake Math, based on a painting by California artist Wayne Thiebaud, features math challenges of many varieties. Elementary-level students (grades 2–5) will practice fractions, addition, subtraction, word problems, sorting, and classifying. Intermediate level students (grades 6–8) will find volume and surface area in Thiebaud's cakes.
This lesson solves word problems on a number line to demonstrate adding and subtracting real numbers that represent temperature change. [Developmental Math playlist: Lesson 141 of 196]
This lesson solves a word problem that involves weight in different units. Also discussed is the importance of knowing that a ton is 2000 pounds for reference. [Developmental Math playlist: Lesson 115 of 196]
