En este módulo de 25 días de grado 4, los estudiantes extienden su trabajo con números enteros. Comienzan con grandes números utilizando unidades familiares (cientos y miles) y desarrollan su comprensión de millones al desarrollar el conocimiento del patrón de tiempos diez en el sistema Base Ten en la tabla de valor del lugar (4.nbt.1). Reconocen que cada secuencia de tres dígitos se lee como cientos, decenas y, seguidas de la denominación de la base correspondiente, mil unidad (mil, millones, mil millones).

English Description:
In this 25-day module of Grade 4, students extend their work with whole numbers.  They begin with large numbers using familiar units (hundreds and thousands) and develop their understanding of millions by building knowledge of the pattern of times ten in the base ten system on the place value chart (4.NBT.1).  They recognize that each sequence of three digits is read as hundreds, tens, and ones followed by the naming of the corresponding base thousand unit (thousand, million, billion).

¡El módulo 4 marca el próximo paso emocionante en matemáticas para los kindergarten, suma y resta! Comienzan a aprovechar sus habilidades de conteo practicadas, conocimiento del valor de los números y trabajan con números integrados para razonar y resolver expresiones y ecuaciones de suma y resta. En los temas A y B, la descomposición y la composición se enseñan simultáneamente utilizando el modelo Number Bond para que los estudiantes comiencen a comprender la relación entre las partes y los entornos antes de pasar al trabajo formal con suma y resta en el resto del módulo.

English Description:
Module 4 marks the next exciting step in math for kindergartners, addition and subtraction! They begin to harness their practiced counting abilities, knowledge of the value of numbers, and work with embedded numbers to reason about and solve addition and subtraction expressions and equations. In Topics A and B, decomposition and composition are taught simultaneously using the number bond model so that students begin to understand the relationship between parts and wholes before moving into formal work with addition and subtraction in the rest of the module.

This task acts as a bridge between understanding place value and using strategies based on place value for addition and subtraction.

This short video and interactive assessment activity is designed to teach second graders an overview of addition (sums to 100) - word problems.

This short video and interactive assessment activity is designed to teach first graders an overview of subtraction (numbers to 100).

This video lecture serves as a review of subtraction up to the number twenty for first graders.

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.

This task was designed to support students to make sense of problems and persevere to solve them (MP1) and understand the relationship between addition and subtraction. Students will solve the take from, change unknown problem, and through a teacher-facilitated discussion, understand that the problem can be solved using addition or subtraction.

The purpose of this task is for students to select 2 numbers from a set of 3 that sum to 9. The task can be completed for sums equaling any number. Teachers may choose to ask students to write the simple equations they select.

In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.

This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.

The purpose of this task is for students to select 2 numbers from a set that sum to 5 (or any other number).

Students gain experience and practice with three types of word problems using the "Take From" context: result unknown, change unknown, and start unknown.

This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.

This resource requires students to present the solution to a multi-step problem in the form of valid chains of reasoning, using symbols appropriately. Students must use their content knowledge of addition and subtraction of mixed numbers with like denominators to reason and solve.

This short video and interactive assessment activity is designed to teach second graders about subtracting 3 numbers - word problems.

This short video and interactive assessment activity is designed to teach second graders about subtracting one-digit numbers - word problems.

This short video and interactive assessment activity is designed to teach second graders an overview of subtraction (numbers up to 20).
