CCSS.Math.Content.1.OA.C.6 Add and
subtract within 20, demonstrating fluency for addition and subtraction within
10.

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.
CCSS.Math.Content.3.OA.C.7 Fluently
multiply and divide within 100, using strategies such as the relationship
between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows
40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from
memory all products of two one-digit numbers.

Of course, fluency with the basic math facts is as
important to higher math as phonics is to reading. Students above 3rd grade who are not fluent
tend to fall further and further behind, something we are working very hard to
prevent. One of the benefits of Math Facts Pro is that you can quickly learn for each student which facts they are/are not fluent in, and then target practice to fix the problem.
