The student will demonstrate the ability to determine and apply the appropriate strategy or strategies that would be necessary to solve various addition problems involving two two-digit numbers by scoring at least 80% on application problems, reviewing and correctly checking the work of a classmate, and scoring 80% on their final assessment.

**Learning Resources and Instructions ** 1. Review addition facts by visiting @http://www.sheppardsoftware.com/mathgames/fruitshoot/fruitshoot_addition.htm

Play levels 1, 2, and 3. Want a challenge, try level 4!

2. Watch the following videos on solving 2 digit addition problems using different strategies (breaking the numbers apart, carrying/regrouping, and using an open number line). As you watch each video, complete the Note Tracker. If you have any questions, review the videos first and if you still have questions, please email me.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">5. **More Practice!** <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;"> Choose five problems from this [|page] and then this [|page]. Solve the problems on paper and then scan your work. Work with your parents to post it on the discussion forum. If you get stuck go back to the previous videos. If you need further help, email me or have your parents to text me right away.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">6. **<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;"> Expert Check! ** <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Check the work of one or more of your classmates on the forum and provide feedback (advice) on their strategy. For example, if a classmate solves 56+23 by first adding the tens and then the ones and then combining the sum of both. Check their work and their answer. Explain to the classmate why their strategy works or doesn't work. Next, offer another way of solving the problem. Want extra credit? Check the work of more than one classmate!

**<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Final Assessment ** <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Let’s see how much you have learned. Download your assessment below. Save it, print it, and follow the directions. After completing your assessment, scan it and email it to wcordy@csdecatur.net. We are aiming for at least 80% or 16 out of 20! Remember to take your time and work out each problem using a strategy that makes the best sense. Check your work! Good luck! You’ve got this and I can’t wait to check your work. <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">
