In first-grade math, we cover composing and decomposing numbers, even & odd numbers, math facts to 20, regrouping tens, place value to the hundreds, comparing numbers, telling time to the half-hour, developing a sense of measurement, and the calendar.
We learn to add 10 more and 10 less on the 120 chart so that we can add double digits by tens, and we practice counting by 2s, 5s, and 10s.
We use a combination of Eureka 1st Grade Math workbook lessons, Happy Numbers digital math, and math games.
