Make First Grade Math Practice Feel Like Play

Early mental math is less about arithmetic than about number sense — knowing that 7 and 3 make 10, that 20 is two tens, that adding and subtracting undo each other. Those relationships are what let a child calculate rather than count, and they are built by frequent short practice rather than by longer sessions.

First grade is where numbers stop being a recitation and become quantities that can be taken apart. The year's real targets are addition and subtraction within 20, number bonds to 10, and reading two-digit numbers as tens and ones. Progress is easiest to see in how a child answers rather than whether they are right: counting every object is early, counting on from the larger number is progress, and answering without counting is fluency.
