This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials A large set of dominoes to affix to a whiteboard or place in a pocket chart, or a regular set to use on a document projector.

Exploring equality -- Mathematics Instructional Plans (MIPs) help teachers align instruction with the 2016 Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.

With this lesson, students will practice the Math Standards of Learning around counting and comparing values of money and creating equations while also learning computer science terminology for problem solving. Students will learn to start counting change with the highest value coin possible.

 This resource is a remix from Illustrative Mathematics.This encourages student collaboration and allows students to have a mathematical dialogue to express their understanding of algebraic properties. This resource is a valuable part of building background when introducing units of measure or equations in the early elementary years of mathematics education as it provides students a concrete example of building an equation with concrete objects.   Suggested Modification- Encourage student online portfolio - A student recording sheet with dominos illustrations can be used as a reference for students to have a mathematical dialogue. Teachers can use online educational platforms that would allow students to record their own understanding of math and share them with the teacher. For example, Seasaw is an educational platform that students can use, but will require parental permission. It allows collaboration between teachers, students, and the parent community where students can have a voice and choice in their learning.   

 I created the Equations True or False Jamboard to give my students practice with identifying equations.  They used a graphic organizer to solve each equation and then sorted it to the true or false column.  You could also have students work the problems on whiteboards.  Before doing the sort, we practiced finding the answers to equations and creating equations that were true.  We talked about the equal and not equal sign and how that might change whether or not an equation is true or false.  This activity supports sol 3.17.   

This 25-day module begins the year by building on student's fluency with addition and their knowledge of arrays. In Topic A, students initially use repeated addition to find the total from a number of equal groups. As students notice patterns, they let go of longer addition sentences in favor of more efficient multiplication facts. Lessons in Topic A move student's Grade 2 work with arrays and repeated addition a step further by developing skip-counting rows as a strategy for multiplication. Arrays become a cornerstone of the module. Students use the language of multiplication as they understand what factors are and differentiate between the size of groups and the number of groups within a given context. In this module, the factors 2, 3, 4, 5, and 10 provide an entry point for moving into more difficult factors in later modules.

This 25-day module builds directly on student's work with multiplication and division in Module 1. At this point, Module 1 instruction coupled with fluency practice in Module 2 has students well on their way to meeting the Grade 3 fluency expectation for multiplying and dividing within 100. Module 3 extends the study of factors from 2, 3, 4, 5, and 10 to include all units from 0 to 10, as well as multiples of 10 within 100. Similar to the organization of Module 1, the introduction of new factors in Module 3 spreads across topics. This allows students to build fluency with facts involving a particular unit before moving on. The factors are sequenced to facilitate systematic instruction with increasingly sophisticated strategies and patterns.
