In this lesson, students explore place value concepts with two-digit numbers as they build and discuss numbers with more ones than tens and more tens than ones.

In this lesson, students strategically create and order two-digit numbers on their game boards to develop the concept of place value.

In this lesson students explore arrays through the context of flats of flowers. Students determine the total number of flowers and write an equation using equal addends. Students calculate the total cost of flats of flowers within 99¢ and represent cost with variations of quarters, dimes, nickels, and pennies.

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.

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.

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.

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.

Prior to this lesson students should have had experiences comparing sets of objects.

The goal of this lesson is to bridge standards CC.6 and MD.2 by comparing sets using measurement concepts and vocabulary.

In this lesson, students will write a survey question, collect data, and explore ways to display data leading to a discussion of the purpose of bar graphs. The second portion of this lesson supports the students’ use of a bar graph. This lesson may take more than one day.

This video examines tips for solving word problems, especially multi-step word problems. These strategies are appropriate for any grade level.
