In this assessment task, students solve a problem using numbers, an equation and explaining their thinking.

For this lesson, students work in pairs to search for the missing addend to complete a mathematical sentence.

For this assessment task, students analyze two equations written in different ways. Students solve both equations and explain their thinking.

This lesson is for grades 1-2 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

This activity takes place after students have had the opportunity to learn strategies such as using place value, decomposing into tens, commutative property, using concrete models, or strategies they come up with on their own to add two numbers together. Students should work in small groups of three or four. Before this activity, students may make a list of strategies they know for adding numbers or they may identify a list already posted in the classroom. Place three or four sets of 0-9 number tiles (digit-cards) in a bag. The first student draws 4 number tiles and uses them to create a 2-digit plus 2-digit addition problem. All students in the group use models, pencil and paper, or whiteboards to solve the problem using a strategy. Taking turns, each student has the opportunity to convince others that the strategy chosen is the best or most efficient for the problem. 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.

For this assessment task, students use a drawing and an equation to solve measurement word problems.

Ck-12's Grade 2 Elementary Math is a series of videos and interactive videos designed to teach basic math concepts to 2nd graders. Concepts covered include Addition and Subtraction, Multiplication, Place Value, Decimals, Time, Fractions, Money, Measurement, and Geometry.

G2M4: Addition and Subtraction Within 200 with Word Problems to 100. Contains 31 Lessons.

G2M5: Addition and Subtraction Within 1,000 with Word Problems to 100. Contains 41 Lessons.

A learning road map is a great way for students and teachers to keep track of standards they have mastered.  This road map is for grade 2 math cluster 2.  It can be printed and placed in a data notebook.  Students would then color in the circle to indicate their level of proficiency.  It could also be used digitally where students would fill in the circle with color.  Road Maps help students take ownership of their learning and help guide instruction for teachers.  This resource was developed as part of a professional learning opportunity funded by the NCDPI Digital Learning Initiative Planning Grant

In this lesson, students add and subtract within multiples of ten based on understanding place value and basic facts.

In this lesson, students add withing 100 using properties of addition to make a ten.

In this lesson, students add and subtract multiples of 10 including counting on to subtract.

In this lesson, students add and subtract multiples of 10 and some ones within 100.

In this lesson, students add and subtract multiples of 10 and some ones within 100.

In this lesson, students use math drawings to represent the composition when adding a two-digit to a three-digit addend.

In this lesson, students relate addition using manipulatives to a written vertical method.
