This task/game allows students to practice addition while also thinking about ways to organize counting by randomly selecting two (two-digit) number cards and finding the sum. In addition, students are prompted with guiding questions to promote discourse. In closure, students use writing to reflect on their learning and thinking strategies during the game.

In Module 4, students develop place value strategies to fluently add and subtract within 100; they represent and solve one- and two-step word problems of varying types within 100; and they develop conceptual understanding of addition and subtraction of multi-digit numbers within 200.  Using a concrete to pictorial to abstract approach, students use manipulatives and math drawings to develop an understanding of the composition and decomposition of units, and they relate these representations to the standard algorithm for addition and subtraction.

In Module 4, students developed addition and subtraction fluency within 100 and began developing conceptual understanding of the standard algorithm via place value strategies. In Module 5, students build upon their mastery of renaming place value units and extend their work with conceptual understanding of the addition and subtraction algorithms to numbers within 1,000, always with the option of modeling with materials or drawings. Throughout the module, students continue to focus on strengthening and deepening conceptual understanding and fluency.

En el módulo 4, los estudiantes desarrollan estrategias de valor en el lugar para sumar y restar con fluidez dentro de los 100; Representan y resuelven problemas de palabras de una y dos pasos de tipos variables dentro de 100; y desarrollan la comprensión conceptual de la adición y la resta de los números de múltiples dígitos dentro de 200. Utilizando un enfoque concreto a pictórico a abstracto, los estudiantes usan manipulaciones y dibujos matemáticos para desarrollar una comprensión de la composición y descomposición de unidades, y relacionan estas representaciones con El algoritmo estándar para suma y resta.

En el módulo 4, los estudiantes desarrollaron fluidez de adición y sustracción dentro de 100 y comenzaron a desarrollar la comprensión conceptual del algoritmo estándar a través de estrategias de valor en el lugar. En el Módulo 5, los estudiantes se basan en su dominio de cambiar el nombre de las unidades de valor del lugar y extender su trabajo con la comprensión conceptual de los algoritmos de adición y sustracción a números dentro de 1,000, siempre con la opción de modelar con materiales o dibujos. A lo largo del módulo, los estudiantes continúan enfocándose en fortalecer y profundizar la comprensión conceptual y la fluidez.
