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.

English Description:
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.

Este módulo final del año de 40 días ofrece a los estudiantes una práctica intensiva con problemas de palabras, así como experiencias prácticas de investigación con geometría y perímetro. El módulo comienza con la resolución de problemas de palabras de uno y dos pasos basados ​​en una variedad de temas estudiados durante todo el año, utilizando las cuatro operaciones. A continuación, los estudiantes exploran la geometría. Estudiantes Tessellate para la experiencia de la geometría de puente con el estudio del perímetro. Las parcelas de línea, familiares del Módulo 6, ayudan a los estudiantes a sacar conclusiones sobre las mediciones de perímetro y área. Los estudiantes resuelven problemas de palabras que involucran área y perímetro utilizando las cuatro operaciones. El módulo concluye con un conjunto de lecciones atractivas que revisan brevemente los conceptos fundamentales de grado 3 de fracciones, multiplicación y división.

In this lesson, students will use keywords and the part-part-whole model to solve addition and subtraction word problems with 2-digit and 3-digit numbers.

In this lesson on addition and subtraction within 20, students learn how to solve addition and subtraction story problems by finding clue words. Adding three addends is also taught in this lesson.

In this lesson, students will use keywords and place value charts to solve addition word problems.

In this lesson on multiplying by eight, students learn about equal groups, explore word problems, and apply their learning to a real-world scenario.

In this lesson on multiplying by five and ten, students learn about equal groups, explore word problems, and apply their learning to a real-world scenario.

In this lesson on multiplying by seven, students learn about equal groups, explore word problems, and apply their learning to a real-world scenario.

In this lesson, students will use key words and the part-part-whole model to solve addition word problems.

In this lesson on money word problems, students learn about the different coins, explore skip counting on number lines, and apply their learning to a real-world scenario.

The purpose of this task is to provide students an opportunity to use mathematics addressed in different standards in the same problem.

The point of this task is to emphasize the grouping structure of the base-ten number system, and in particular the crucial fact that 10 tens make 1 hundred.

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes.

Move and play with these activities from Peg + Cat! From playing hide and seek and imagining pirate stories to dancing like Misty Copeland, you will find a treasure of fun ideas in these five printable activities.

This word problem requires students to use addition and subtraction and think about money.

The purpose of this task is to have students add mixed numbers with like denominators. This task illustrates the different kinds of solution approaches students might take to such a task.
