This task is focused on Common Core Standards 3.OA.3 Students are applying understanding of multiplication concepts to solve a multi-step word problem related to a real life context. This is a good beginning task to help students show all their work using equations to represent the solution path for the task. It also helps students focus on precision as they need to represent the problem with the correct equations.

In this task, the students are not asked to find an answer, but are asked to analyze word problems and explain their thinking. In the process, they are faced with varying ways of thinking about multiplication.

Students bury various pieces of trash in a plotted area of land outside. After two to three months, they uncover the trash to investigate what types of materials biodegrade in soil.

Students will engage in constructed response contextual tasks involving multiplication and division. Tasks include a variety of problem situations (e.g., unknown product, unknown group size, or unknown number of groups) of increasing complexity. Students will represent their thinking in multiple ways (e.g., pictorially, symbolically, or textually) to demonstrate conceptual understanding.

In this video segment from Cyberchase, Inez and Lucky figure out how to keep track of the number of clones as they continue to multiply.

The purpose of this task is for students to "Solve problems involving the four operations" (3.OA.A) and "Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories" (3.MD.3). Additionally, students will engage in MP3, Model with mathematics. In this task students are asked to decide how to spend $1,000 on supplies and materials for their classroom; students will have to make choices and be careful not to exceed the budget. Students are asked to decide which supplies will benefit the class the most and will compare their choices with other students' choices.

Students who work on this task will benefit in seeing that given a quantity, there is often more than one way to represent it, which is a precursor to understanding the concept of equivalent expressions.

In this Cyberchase video segment, the CyberSquad figures out how to earn 100 snelfus in 11 days.

The first of these word problems is a multiplication problem involving equal-sized groups. The next two reflect the two related division problems, namely, "How many groups?" and "How many in each group?"

This 25-day module begins the year by building on students’ fluency with addition and knowledge of arrays.

This 25-day module builds directly on students’ work with multiplication and division in Module 1. 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.

Students investigate how old the universe is and when important events took place in the universe and on Earth. They draw the universe timeline from the beginning until today on the scale of a year.

Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.

In this video segment from Cyberchase, Inez estimates whether she has enough jelly beans in her large container to decorate all of the cookies in her batch.

In this Cyberchase video segment, Matt and Jackie must figure out which combination of knob and key will get them one step closer to retrieving the Black Crystal.

Every month we will give you a math/statistics brain teaser that lets you test your knowledge with a fun problem.Many of the ideas in these Teasers come from thoughts formed by some of the great mathematical/statistical geniuses in history.

Este módulo de 25 días se basa directamente en los estudiantes que trabajan con multiplicación y división en el módulo 1. El módulo 3 extiende el estudio de factores de 2, 3, 4, 5 y 10 para incluir todas las unidades de 0 a 10, así como múltiples de 10 dentro de 100. Similar a la organización del Módulo 1, la introducción de nuevos factores en el módulo 3 se extiende a través de temas. Esto permite a los estudiantes construir fluidez con hechos que involucran una unidad en particular antes de continuar. Los factores están secuenciados para facilitar la instrucción sistemática con estrategias y patrones cada vez más sofisticados.

In this engaging unit, students will design and plant a square-foot garden that will be their central tool. Through the growing season, they will explore nutrition content in their everyday lives and see how it relates to what they are growing.
