Description: This bundle includes various opportunities for students to practice the addition fact strategy "doubles" and "near doubles". Students use memorization to answer doubles facts and mental math to answer doubles plus 1 and doubles plus 2 facts. The Boom Card decks include the following: Doubles Deck 1 (includes visual representation) Doubles Deck 2 (used for fluency) Near Doubles Deck 3 (doubles plus 1) Near Doubles Deck 4 (doubles plus 2) Near Doubles Deck 5 (doubles plus 1 and 2) Near Doubles Deck 6 (used for fluency) Near Doubles Deck 7 (select the correct doubles fact for plus 1) Near Doubles Deck 8 (select the correct doubles fact for plus 2) Near Doubles Deck 9 (select the correct doubles fact for near doubles) CCSS.MATH.CONTENT.1.OA.B.3 Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.) CCSS.MATH.CONTENT.2.OA.B.2 Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
