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 aspects of the task and its potential use.

Water is a natural resource that is limited and needs to be conserved.  Students will collect data about how much water they are using at home, design a plan to conserve water, implement the plan, and again take data to determine their success.

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.

Multiplying with 0, 1, 2, 5, and 10 --  Mathematics Instructional Plans (MIPs) help teachers align instruction with the 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.

I created this game to give my students a fun way to practice multiplication!  3rd grade students should participate in meaningful activities to develop an understanding of multiplication and become fluent with their multiplication facts.  This activity supports sol 3.4c, demonstrate fluency with multiplication facts of 0, 1, 2, 5, and 10 and sol 3.4a, represent multiplication and division through 10 × 10, using a variety of approaches and models.  The students make a big circle around the room and play a cakewalk style game and draw pictorial models.  This game should be played after students have had experiences in the classroom working with manipulatives to practice the different approaches and strategies for multiplication.  Movement is an effective way for students to learn and I can easily assess them while they play the game.  My students love this game and ask to play it all the time!
