In this lesson students solve a problem where skip counting by 5s and 10s is required to solve a real world problem. Students have some previous practice with skip counting to numbers beyond 100.

In this lesson, students build pattern block animals inspired by literature, describe and graph the shapes used, and interpret the data by asking and answering questions to develop the concepts of geometry and graphing.

Students are asked to solve a real world problem, show their work using pictures, numbers or words, and record a matching equation. A scoring rubric is included. The task may be used for instructional or assessment purposes.

In this lesson, students will identify how many manipulatives are in a given arrangement without counting each individual object (focus on 1-5). Students will understand the relationship between numbers and quantities, and will explain this relationship as they determine "how many" are in a set.

Note: Perceptual subitizing means to instantly recognize "how many" in a set.

"Perceptual subitizing" is instantly knowing an amount without counting each individual item. These perceptual subitizing cards can be used with Numbers Talks, games, or as a quick warm-up at the beginning of a lesson.

In this lesson, students use ten frame cards to compose numbers within 100 and compare numbers.

Arrow cards are a great tool for developing an understanding of place value! In this lesson, students explore making numbers with place value materials and arrow cards. The develop the concept that the digits of a number represent amounts of tens and ones.

A Number Talk is a brief routine (about 10 minutes) focused around developing flexibility and fluency with numbers. Through regular opportunities to work with dot images and expressions, students develop an understanding of number relationships and structure. This supports the development of early fluency skills.

This PowerPoint contains presentation slides for daily Number Talks, as well as directions and videos for implementation. Teachers may facilitate the Number Talks on these slides, or use them to inspire their own Number Talks based on student need.

In this lesson, students build fluency with recognizing and creating representations of numbers within 100. Students deepen their place value understanding as they work with ten frame cards. There are several variations built into the lesson for number ranges and response options.

In this lesson, students use square tiles to create rectangles using the vocabulary rows and columns. They write an equation to represent the total.

This file contains representations and strategies for solving comparison problems. These representations help answer the questions, "How many more?" and "How many fewer/less?" This resource is especially useful for making comparisons when analyzing data.

In this lesson, students will identify the number of objects in a group as greater than, less than, or equal to the number of objects in another group, for numbers 1-5. Students will understand the relationship between number labels (such as "4" naming a collection of four) and quantities. They will understand that counting by ones increases the quantity by one more.

In this lesson, students use their understanding of word problems to sort problems based on type. The focus for students in this lesson shifts from solving word problems to analyzing word problem structures in order to group like problems. The purpose is to help students understand and visualize problems so they will know how to write equations that match and know what operation is needed to solve. This lesson focuses on sorting addition and subtraction word problems with a specific focus on Take Apart and Put Together types. The lesson, however, can be adjusted to use with any problem types you notice students need more experience with. You could also adjust the number size in the problems to use this lesson at different times in the year.

Students find objects that are longer than, shorter than, and the same length as a given straw. This task may be used for instructional or assessment purposes.

In this lesson, students use number cards to create the highest two-digit numbers possible to develop the concept of using place value to compare numbers.
