Fourth Grade Math

Throughout the school year, 4th grade students will spend the most time working on the following topics. They should understand them well by the end of the year. 

• Using the four operations, solve multi-step word problems that use whole numbers and have whole number answers, including problems where students make sense of remainders. (For example: Four classes are going on a field trip. The classes each have 28 students. Buses hold 48 passengers. If all of the students, 4 teachers and 4 chaperones are going on the field trip, how many buses will they need?)

• Adding and subtracting multi-digit numbers with ease (23,647-5,265)

• Multiplying and dividing multi-digit numbers in problems with a limited number of digits (1, 638 x 7 or 24 x 17; 6,966÷6)

• Understanding and applying equivalent fractions (recognizing that ¼ is less than ⅜ because ¼ equals 2/8, and two eighths are less than three eighths).

• Adding, subtracting and multiplying fractions in simple problems ( 2 ¾ - 1 ¾ or 3 x ⅝) and solving related word problems that include fractions in context. (For example, you are going to make cookies for a party. You need 2.3 cup sugar for one batch and decide to make 8 batches, so all your neighbors can have a cookie. How many cups of sugar do you need?) 

• Understanding and explaining simple decimals in terms of fractions (rewriting 0.62 as 62/100)

• Practice adding and subtracting (multi-digit numbers) and multiplying and dividing, two digits by two digits (32 x 68; 89 ÷ 47) and up to four digits by one digit (1,200 x 8; 1,800 ÷ 9).

• Practice adding and subtracting fractions with the same denominator (4/10 + 3/10; 56/100 - 22/100).

• Encourage a positive mindset about mathematics in the real world. This can be done by cooking with your child and asking them to help you measure the ingredients for a recipe.
