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 activity is designed to determine the appropriate instructional level for a student in a one-on-one interaction with the teacher.

In this assessment in a one-to-one setting, a student is shown the numbers from 1Đ10, one number at a time, in random order. The teacher asks, Ňwhat number is this?"

This assessment task can be used with a single student or a small group of students. Each student needs his or her own set of numeral cards.

This assessment may be used in a small group or whole group setting, give each student a piece of paper. Students who have trouble writing certain numbers can then get targeted practice.

This task supports students in correctly writing numbers. Because students have to trace the number, instead of coloring in a bubble with the number in it or circling the correct number, they gain handwriting practice as well as counting and addition practice.

This game will reinforce number before and after as well as reading and sequencing numbers.

Up to this point in Grade K, students have worked intensively within 10 and have often counted to 30 using the Rekenrek during fluency practice. This work sets the stage for this module where students clarify the meaning of the 10 ones and some ones within a teen number and extend that understanding to count to 100.

This counting activity is done in pairs and helps reinforce the concepts of greater than, less than, and equal to.

Hasta este punto en el Grado K, los estudiantes han trabajado intensamente dentro de 10 y a menudo han contado a 30 utilizando el Rekenrek durante la práctica de fluidez. Este trabajo prepara el escenario para este módulo donde los estudiantes aclaran el significado de los 10 y algunos dentro de un número adolescente y extienden esa comprensión para contar hasta 100.

This number after bingo activity increases student flexibility with the number sequence and their ability to start counting sequences at various points.

This number line up activitiy gets students out of their seats and helps reinforce the counting sequence.

This activity is played in pairs and gives students practice reading numbers out loud and tracing them.

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.

This game game supports students in counting forward and can be adjusted to support backward counting.

This is a choral counting activity that can be easily adjusted as students learn higher numbers.

The Playful Learning Challenge's Pre-K and Kindergarten Math Activities Kit contains a series of 10 research-based early math activities centered around play, that can be used with simple materials in children's classrooms or homes.
