This resource is from Tools4NCTeachers.In this lesson, students will explore a variety of strategies to find the missing number needed to make ten.  They will represent their work using objects, drawings, and numbers.  This lesson uses the Launch, Explore, Discuss lesson format.Remix this lesson to share your ideas for extending this lesson or upload student work-samples.

This resource is from Tools4NCTeachers.Students will identify and record mystery numbers with partners.  They will organize quantities of objects into ten ones and some extra ones, developing an understanding of how ten ones and some extra ones can be combined to make a total.  Further, students will tell how two quantities are the same and different (example: One group of seventeen ones verses a group of ten ones in a ten frame and seven ones on the outside of the frame.)

In this lesson, students are introduced to Number Talks involving dot cards. Students develop efficient strategies for finding "how many" dots are on each card. Strategies relate to first grade addition concepts.

This resource is from Tools4NCTeachers.This lesson calls for students to verbalize that ten objects is the same as a set of ten. They will compose teen numbers as ten ones and some extra ones, and combine the amounts on and off the ten frame to make a total.Remix this lesson to add accompanying math centers, extension ideas, or samples or student-work.

This task assesses student's understanding of place value with teen numbers. Task may be used for instructional or assessment purposes.

This resource is from Tools4NCTeachers.In this lesson, students analyze a picture of animals in the barnyard. Students use the context to create both addends unknown combinations to make 10. They show their thinking and record their decompositions using objects, words or drawings.Please remix this lesson to share your ideas for other problems, extensions, related math stations, or samples of student work.

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.

This resource is from Tools4NCTeachers.This lesson calls for students to organize a group of objects into ten ones and some extra ones. They will develop an understanding of how ten ones and some extra ones can be combined to make a total. Students will count on from ten to determine how many there are all together in a group.  

This resoruce is from Tools4NCTeachers.Second graders use a variety of strategies based on place value and number relationships to add and subtract multi-digit numbers.  The first attachment in this resource outlines strategies for adding 3-digit numbers, and the second attachment outlines strategies for subtracting 3-digit numbers.Second graders are not taught the standard algorithm.

In this lesson, students "notice" and "wonder" as they look at a real world photograph. Then, they use a variety of representations to solve a problem related to the photo.

By the end of this lesson, students should be able to solve a
"put together, take apart" word problem by decomposing 8 in a variety of ways.

This resource is from Tools4NCTeachers.In this lesson, students are given boxes to cut apart.  As they decompose the boxes, students notice the 2-dimensional shapes used to construct their 3-dimensional boxes.  A printable student recording sheet is provided within this lesson.Remix to include pictures of student work samples. 

In this assessment task students will solve a story problem using a Ten Frame. Students can use math manipulatives if they need to, explain their thinking or the teacher can take a picture as evidence that the student is proficient with the task of decomposing numbers 11-19. Students are also asked to write a number sentence as a part of this task. An assessment sheet and rubric are provided.
