Included are 1st Grade Smartboard Lessons for Engage NY Common Core Math - D Lessons (13-18): Addition of Tens or Ones to a Two-Digit Number
I copied the Application Problem and added movable images (such as 10 sticks, pennies/dimes, linking cubes, ...) so that after students complete the problem on their personal whiteboards they/the teacher can show how to solve the problem on the Smartboard. I also added math tools for Concept Development, screen shots of the Problem Sets so you don't have to switch between your DocCam and the Smartboard, and the Student Debrief questions. Last, I added website links to games, videos and and/or related math activities.
Objective 1:Use counting on and the make ten strategy when adding across a ten.(Lessons 13–14)
Objective 2:Use single-digit sums to support solutions for analogous sums to 40.(Lesson 15)
Objective 3:Add ones and ones or tens and tens.(Lessons 16–17)
Objective 4:Share and critique peer strategies for adding two-digit numbers.(Lesson 18)
Common Core Standard: 1.NBT.4. Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
