Product Description
This unit is part of the addition portion of the Mental Math Strategy Collection.

Mental Math Units: the Complete Addition Collection

Doubles Plus One equations include facts such as 5+6 and 7+8. Using the doubles plus one strategy, a student begins with a known double and adds one more. For example, in the equation 7+8, a student could think "I know that 7+7=14 and one more = 15, so the answer is 15."

Did you know that when a student knows his doubles and doubles plus one facts, he knows more than 25% of the addition table?

This mental math strategy pack includes everything you need to help your students develop strategies for and learn the doubles plus one facts. Included is independent seat work, flashcards, center activities, kinesthetic learning activities and much more! Please see the free preview for a complete product description.

Enjoy!
