  1. Mrs. Whalen’s Kindergarten Math Lesson #34: Different ways to add

  2. Daily Practice!

  3. Let’s watch! In our last lesson we learned how to add numbers together. Let’s practice adding 1 to a number. https://www.youtube.com/watch?v=sxW9gsVWhVA

  4. Adding by 1 is so much fun. Now let’s look at adding by 2’s. Let’s watch! https://www.youtube.com/watch?feature=fvwp&v=D39v6YqeJRA&NR=1

  5. Let’s look at some more problems. 3 + 1 =

  6. 3 + 1 = 4

  7. Let’s look at some more problems. 3 + 2 =

  8. 3 + 2 =5

  9. Let’s look at some more problems. 4 + 1 =

  10. 4 + 1 =5

  11. But what if we are adding zero? 5 + 0 =

  12. Now let’s look at adding zero. Let’s watch! https://www.youtube.com/watch?v=ikeNNn6m38k

  13. Lesson

  14. Did you know that 2+1=3 is the same as 1+2=3? 1+2=3 2+1=3

  15. Yes. They both equal the same thing. 3 1+2=3 2+1=3

  16. That is called turn around math. When you switch the places of the two groups you are adding you still get the same answer. 2+3=5 3+2=5

  17. Now let’s watch a video about turn around math. Let’s watch! https://www.youtube.com/watch?v=KfjXD8skB-0

  18. Also when you are talking about math facts that are equal, you can say 5= 1+4. That is the same things as saying 1+4=5

  19. Are these facts equal? 3+0=3 0+3=3

  20. Yes, they are equal. They both equal 3. 3+0=3 0+3=3

  21. Are these facts equal? 2+2=4 1+3=4

  22. Yes both of these facts equal 4. 2+2=4 1+3=4

  23. Let’s make groups of coins on the document camera. We can see many ways we can make addition facts that are equal.

  24. Practice!

  25. Now let’s look at a fun addition rock song. Let’s watch! https://www.youtube.com/watch?v=auem1DFtDrY

  26. Now let’s look at another fun addition rock song. Let’s watch! https://www.youtube.com/watch?v=Nhp8-Q8xMfo

  27. Using coins or beans and come up with 2 ways you can make addition facts using 5 beans. How can you divide the beans or coins into 2 groups?

  28. Use the 2 circle template I used in my document camera lesson to help you divide your objects.

  29. Good job today! In our next lesson we will look at the numbers 51-60.

  30. Goodbye! See you next time!
