Grade 2 Fact Fluency Plan—2.OA.B.2 Daily practice of each strategy is encouraged. This can be done as a paper-and-pencil activity, or as a game with the tools listed below. Teachers may want to begin whole group mathematics lessons with five minutes of fluency practice, with students responding on white boards to check for student understanding, and for students to explain their thinking. In addition, consider finding time once each week (10-15 minutes) to allow students to practice in pairs or small group, while providing targeted intervention for students who have not yet mastered a strategy. Some general materials are useful to build fact fluency: ten frames dominos dot cards/dot plates dice playing cards “I have…, Who has…” decks Songs, chants, rhythms with physical movement and/or showing numbers with hands/signs can also be effective. Assessments are included/linked, and are designed to be given (bi-)weekly to monitor student progress. Students should be given 2 minutes to complete the test. It is suggested to give students the “FINAL” test throughout the year to progress monitor with a standard assessment. Suggested Time Line—can/should be adjusted based on student readiness Weeks 1 & 2 Week 1 Strategy Description Examples Suggested Activities ALL +1/-1 Created 7/2015 Students build on their understanding of counting on to add 1 more or counting back to find 1 less.

Students can draw part of a number line to model: 2 jumps to the left to find 2 less, and 2 jumps to the right to add 2 to any number. Adding 10 to a single-digit number results in a 2-digit sum. Students should build understanding and automaticity that will be needed during “using tens” strategy as well as the foundations of place value when composing ten and a single-digit number or decomposing a teen number to 10 and a single digit number.

I can take 1 from the 7 and add it Use Tens to the 9 to make 10. Then I have 6 left from the 7, and 10 + 6 = 16. 8 + ? = 14 I know 8 plus 2 more equals 10, and then 4 more makes 14, so 8 + 6 = 14 Using Ten Notes & Games: Who Has More Condition High and Low Addition BINGO Take Away Match ‘Em Up Description Examples Suggested Activities Week 25 Review familiar games Review +1/-1 +0/-0 +2/-2 +10/-10 Doubles Make 10 Use 10 Created 7/2015 Assessment T13 Plus 1/Minus 1 Plus 0/Minus 0 Plus 2/Minus 2 Plus 10/Minus 10 Doubles Make Tens Use Tens Page 5 of 22 Grade 2 Fact Fluency Plan—2.OA.B.2 Weeks 26-28 Use Doubles Weeks 29-37 Use doubles facts to find unknown facts that are near doubles, where the difference between the addends is 1 or 2. Review ALL 4+5=_ 13 = 7 + _ Think Aloud and model with domino T14 doubles: 4 + 5 = ? Use Doubles I know that 4 + 4 = 8, and 5 is 1 more than 4, so my answer is 1 more than 8, so it’s 9. 13 = 7 + ? I know that 7 + 7 = 14, and 13 is one less, so if I take 1 less than 7, that is 6. 7 + 6 = 13.
