For this assessment, students are asked about what they would purchase at the store given a set amount of money and prices.

In this lesson, students will compare the efficiency of counting by ones and counting by tens.

In this lesson, students recognize and make use of part–whole relationships within tape diagrams when solving a variety of problem types.

In this lesson, students count and write numbers to 120 and use Hide Zero cards to relate numbers 0 to 20 to 100 to 120.

In this assessment, students demonstrate their ability to use place value understanding and properties of operations to add and subtract, as well as represent and solve problems involving addition and subtraction.

Students play a game in pairs to read and recognize numbers using a 100 chart.

Students will be presented with a problem that they have a non-English speaking student in their classroom and it will be their job to create a means for teaching their classmate how to add. They will work in groups of 3 or 4 to plan and design an activity or a display (or both) that models the addition process within 20. Students will work primarily on learning the collaboration process during this initial PBL project. They will learn skills related to group work, group accountability, and the creation of a single group product. They will be introduced to the Critical Friends protocol. Students will do a first draft and a final product to learn that process. They will present to the class.

This is the About the Cluster document written by the NC2ML group who created the instructional frameworks. This is a great resource to read while starting to plan for First Grade Cluster 2.

In this interactive, students are presented with a blank hundred chart. Students help the monkey find the fireworks by selecting the box which represents the number given by the monkey. The more fireworks students find, the more they will have to launch at the end of the game.

In this assessment task students will read and answer the riddle, then they will use place value, addition and subtraction to determine the answer to the riddle. An assessment task sheet and rubric are provided.

This unit of 1 Number and Operation lessons explores numbers and place value to 120. The unit contains 4 activities.

This unit of 1 Number and Operation lessons explores place value through 3 hands-on activities.

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.

In this Khan Academy interactive, students will be able to count to 120 starting at any number and find the numbers before and after any number.

Students will observe the base ten representation and choose the correct numeric representation in this interactive.

Students work in teams to follow criteria and constraints to design their own container that holds pompoms (popcorn). When this is completed they need to test and record how many pom-poms their container will hold. Students find that counting and organizing groups of ten is the best way to do this. They record their information on a data analysis sheet and the following day they compare their numbers and amounts.
