This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Louis wants to give \$15 to help kids who need school supplies. He also wants to buy a pair of shoes for \$39.

This parent guide supports parents in helping their child at home with the 2nd Grade Math content.
This resource accompanies our Rethink 2nd Grade Math Number & Operations in Base Ten unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.
This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Math for Number & Operations in Base Ten.
The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of selected math standards. Each video is an audiovisual resource that focuses on one or more specific standards through examples and illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard, although the examples can be adapted for instructional use.

In this Khan Academy interactive, students will add ones or tens to a two-digit number.
In this Khan Academy interactive, students will add two-digit numbers to two-digit numbers.
By now students have worked with many strategies to add and subtract numbers. Students will work in pairs. One student will think of an addition or subtraction problem and choose an efficient strategy to solve the problem. Then the student will give the problem to the other student who will solve the problem and explain his/her strategy to the partner. The problem poser will ask questions about the explanation or tell how the strategy matched the strategy he/she used. Students will discuss the benefits of a particular strategy. Then the other student will pose the next problem. The students will keep track of strategies used and try to create problems that will allow them to use more than one strategy. For the last few minutes of the activity the pairs can share out the different strategies they were able to use and explain. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

In this activity, students will solve a subtraction problem with Base 10 blocks and post their work to SeeSaw. The Number Pieces App allows students to manipulate base 10 blocks electronically to show their understanding of counting concepts.
In this assessment task, students solve a problem using numbers, an equation and explaining their thinking.
Bee-bot is trying to learn Math. Students will follow Bee-bot solving a math problem. It will solve the problem incorrectly. Students will find where the mistake occurs and correct Bee-bot’s program to help him solve it correctly.

In this Khan Academy interactive, students will add two-digit numbers with multiples of tens and some ones by decomposing them.
In this lesson, students first listen to the story Bunny Money. They then work in pairs to add sets of three single-digit numbers to determine the value of their savings goals and total savings. They compare the values to determine whether they have saved enough to meet their savings goals. Finally, students calculate the difference between the value of their savings goals and total savings.
