During 1st grade, children will then learn addition and subtraction facts, two-digit numbers, some adding and subtracting with two-digit numbers, and some basics of measuring, time and money.
If the two values being subtracted are mixed fractions, it is often easier to turn them into improper fractions to perform the subtraction. This avoids any kind regrouping or borrowing from the minuend fraction if the numerator in the subtrahend is larger.
Once you have built an understanding of the concept of division you can try using these division worksheets. When teaching early division you should also discuss that division has an opposite. Discuss how division is about separating sets, while the opposite type of math, called multiplication is about combining sets. Explore this relationship with your child as it will be important when recalling basic facts to solve division problems. Introduce fact families (e.g. 5 x 3 =15, 3 x 5 = 15, 15 ÷ 3 = 5, 15 ÷ 5 = 3).
Division with remainders. Your child will most likely come across or ask about situations where division “does not work.” These can be explained with the introduction of the remainder. It is an important idea to understand as the division of larger numbers will require the “carrying” of this remainder.
