Lesson 26 Learning Objectives:
Find differences in addition and subtraction sequences mentally, by counting on fingers or by using a number line
Solve simple problems using increasing sequences
Find the multiplier between two numbers by skip counting on fingers or using multiplication charts
Extend addition, subtraction, and multiplication sequences

Reflect:
Reflect in your math journal. Draw, create or write to share your thinking. See Lesson 1 plan for more reflection questions, real life anchoring, playful explorations and creative invitations.
The sequence is 6, 12, 18, ___. What do you notice? How can you figure out what comes next using your fingers or a number chart?
Two friends count: one says ‘add 5 each time,’ the other says ‘skip count by 5.’ Are they both right? Why or why not?
Describe the strategies that you use for skip counting? How would you teach a peer who is learning about skip counting with numbers 2-9?
When you count on your fingers or move along a number line, how does your body help your mind “see” the difference or the jump between numbers?
Math Talk:
Have a conversation about this image. Be curious. Be creative. Can you see in different ways?
What numbers and patterns do you notice? How and what can you count? What relationship do these number lines have to addition and multiplication? What is the same and what is different?
