In this activity, students are given clues about a mystery number card. Students listen to the clues, find the corresponding quantity, and then identify the matching numeral. The goal of this activity is to develop flexibility in representing numbers in a variety of ways.

In this lesson, students create a "train" (or row) of shapes. Each shape in the row must have one attribute in common with the shapes on either side.

In this lesson, students build three-dimensional representations of shapes. They discuss attributes of their shapes, and predict if their shapes will roll, slide, or both.

Kindergartners need lots of opportunities to explore, investigate and to discuss the different properties of both two and three dimensional shapes. As students learn more geometric content, they will begin to be more sophisticated in their ways of thinking.

In this lesson, the students will explore even and odd numbers through a variety of hands-on learning activities. Students will explore numbers up to 100, comparisons of groups, and odd/even relationships of numbers up to 20.

In this lesson, students explore counting patterns to develop place value understanding. Students use tools such as number lines, and a hundred chart. Additionally, the explore patterns within real world situations.

In this lesson, students explore equality using the equal sign. They will first explore equality with sets or groups using the equal sign then move to exploring equality with equations. The lesson could be taught consecutively in one math block but may need to extend over multiple days depending on student understanding of the concept of equality, or having equal amounts. The lesson could also be modified or extended by repeating tasks and discussion with more emphasis on subtraction.

In this lesson, students will use perceptual subitizing* as an efficient method for determining "how many". Through experiences, students will subitize sets within five.

*Perceptual subitizing: instantly recognizing "how many" in a set
*Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set.

This purpose of this lesson is to give students the opportunity to problem solve and analyze other students' solutions while using a number line.

This resource is from Tools4NCTeachers.This resource contains a set of two PowerPoints (one for two-dimensional shapes and one for three-dimensional shapes).  Each PowerPoint contains several activities and tips for exploring geometry and developing vocabulary. These PowerPoint slides may be used to support the development of lesson plans or provide proessional development to teachers.

This is lesson six in a series of six lessons focused around developing a mathematical community at the beginning of the school year. The goal is to promote the idea that it is okay to make mistakes in math as long as we try to figure out the mistake and fix it.

This resource is from Tools 4 NC Teachers. In this lesson, students will play a game and see multiplication as combining equal groups, use repeated addition and other strategies to find the total number of stars, and record answers by writing equations.

This lesson is from Tools 4 NC Teachers. In this lesson, students explore multiplication and division concepts through the use of numberless word problems and use various strategies to solve a second problem.

This lesson is from Tools 4 NC Teachers. It was written with the intent that it would be taught on Day 10 of Cluster 1. In this lesson, students explore the concept of multiplication by thinking about things that come in groups. They connect equations to story problems that involve equal groups, use various strategies to solve those problems, and share their thinking by communicating their reasoning and sharing solutions.
