Lisa,

Thank you for your message, I apologize for the delay in responding as I think I need to ask for your guidance!

I spoke with Dr. Cotter and looked at RSB Lesson 76 and am not seeing anything with "the near ten strategy" in that lesson, could you please guide me to where you read that in the lesson? We are not showing that the term "near ten strategy" occurs in Level B.

As far as the two 5's strategy, that is done in RSB Lesson 66, which can be explained as: This strategy for a sum, such as 6 + 7 involves seeing 6 as 5 + 1 and 7 as 5 + 2. The two fives make 10; the 1 and 2 make 3; thus, the answer is 10 + 3 = 13. There is trading quantities involved.

I hope this makes the two 5's strategy more clear, but please let me know where in Lesson 76 we were discussing the "near ten strategy" so we can clear up any confusion!

I look forward to hearing from you! Make it a great day!

Cassie
