Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

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 asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials Set of cards from 1-100, these can be purchased or created using a black marker and index cards Setup Sort the 1-100 cards into sequential gr...

An interactive applet and associated web page that demonstrate the the concept of adjacent arcs. The user can 3 drag points around a circle that define the endpoints of two adjacent arcs. Web page has the properties of adjacent arcs. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Teachers (and then students) lead the class in chanting numbers from 1 to 120.

Students practice counting sequences by standing in a circle and counting one by one.

Students practice crossing from one family to the next in counting forward with this concentration game.

Module 4 builds upon Module 2’s work with place value within 20, now focusing on the role of place value in the addition and subtraction of numbers to 40.  Students study, organize, and manipulate numbers within 40.  They compare quantities and begin using the symbols for greater than (>) and less than (<).  Addition and subtraction of tens is another focus of this module as is the use of familiar strategies to add two-digit and single-digit numbers within 40.  Near the end of the module, the focus moves to new ways to represent larger quantities and adding like place value units as students add two-digit numbers.

In this final module of the Grade 1 curriculum, students bring together their learning from Module 1 through Module 5 to learn the most challenging Grade 1 standards and celebrate their progress. As the module opens, students grapple with comparative word problem types. Next, they extend their understanding of and skill with tens and ones to numbers to 100. Students also extend their learning from Module 4 to the numbers to 100 to add and subtract. At the start of the second half of Module 6, students are introduced to nickels and quarters, having already used pennies and dimes in the context of their work with numbers to 40 in Module 4. Students use their knowledge of tens and ones to explore decompositions of the values of coins. The module concludes with fun fluency festivities to celebrate a year's worth of learning.

El módulo 4 se basa en el módulo 2 s trabajo con el valor del lugar dentro de 20, ahora centrándose en el papel del valor del lugar en la adición y resta de los números con 40. Los estudiantes estudian, organizan y manipulan números dentro de los 40. Comparan cantidades y comienzan a usar Los símbolos para mayores que (>) y menores de (<). La adición y la resta de TENS es otro foco de este módulo, al igual que el uso de estrategias familiares para agregar números de dos dígitos y de un solo dígito dentro de 40. Cerca del final del módulo, el enfoque se mueve a nuevas formas de representar grandes cantidades y agregar Al igual que las unidades de valor colocadoras, ya que los estudiantes agregan números de dos dígitos.

En este módulo final del plan de estudios de Grado 1, los estudiantes reúnen su aprendizaje del Módulo 1 al Módulo 5 para aprender los estándares de Grado 1 más desafiantes y celebrar su progreso. A medida que se abre el módulo, los estudiantes lidian con tipos de problemas de palabras comparativas. A continuación, extienden su comprensión y habilidad con decenas y números a 100. Los estudiantes también extienden su aprendizaje del módulo 4 a los números a 100 para sumar y restar. Al comienzo de la segunda mitad del módulo 6, los estudiantes se introducen en los monedas de montaña y cuartos, ya que ya han usado centavos y diez centavos en el contexto de su trabajo con los números a 40 en el módulo 4. Los estudiantes usan su conocimiento de decenas y otras para explorar las descomposiciones de los valores de las monedas. El módulo concluye con festividades divertidas de fluidez para celebrar un año de aprendizaje.

Students learn the connection between the counting sequence and experience from their daily lives in this daily activity. It also helps give students a sense of how "many" each number is.

The intent of clarifying statements is to provide additional guidance for educators to communicate the intent of the standard to support the future development of curricular resources and assessments aligned to the 2021 math standards.  Clarifying statements can be in the form of succinct sentences or paragraphs that attend to one of four types of clarifications: (1) Student Experiences; (2) Examples; (3) Boundaries; and (4) Connection to Math Practices.

The purpose of this task is to address the concept of opportunity cost through a real world context involving money.
