Go Math 3rd Grade Chapter 8 Review Test

Want to help your third-grader principal the basics of 3rd grade math? Here are some of the skills your kid will be learning in the classroom.

Addition, subtraction, multiplication, & partitioning

Multiplying numbers

Sympathise what it ways to multiply numbers – for instance: five x 3 can be thought of equally the full number of objects in 3 groups where each group contains 5 objects – or the total number of objects in five groups where each group contains three objects. Relate the concept of addition to multiplication.

Times table

Know the times table. By the end of third grade, quickly and accurately multiply any one-digit number by any other one-digit number.

Tip: Play math games

Time spent commuting or waiting in a auto is a nifty opportunity to play math games with your child. Multiplication is one of the key math concepts she is working on in school and you tin can help her practice by asking her elementary multiplication issues that relate to real life. Ask her to effigy out the number of days until an event iii weeks from today. Or have her summate how many weeks she would have to relieve her assart to buy a toy or game she wants.

Multiplication and addition

Apply knowledge of add-on to understand that 4 x 7 is the aforementioned as 4 x 5 + 4 ten 2.

Dividing numbers

Empathise that dividing numbers can exist looked at as separating numbers of objects into equal groups.

The human relationship

Understand the human relationship between multiplication and division. For case, understand that if 9 x iii = 27, then 27 ÷ nine = 3, and 27 ÷ 3 = 9.

Partition with an unknown

Solve sectionalisation bug involving an unknown – for example, solve 27 ÷ 9 = ? by thinking 9 10 ? = 27.

Understanding place value

Use understanding of place value to add, subtract, multiply and divide multi-digit numbers.

Solving give-and-take problems

Solve word problems involving multiplication and partition of numbers within 100.

Example:

The 2d-grade class and 3rd-grade class were collecting one-time jail cell phones to recycle. The third grade class nerveless 10 old cell phones. The second form grade collected twice (two times) that number. How many cell phones did the second course class collect?

The second-course class decided to divide their nerveless cell phones as between five different charities. How many phones will each charity get?

Fractions

Fractions as numbers

Empathise fractions as numbers. Using visual models or number lines (example below), empathize that ii fractions are equivalent (equal) if they are the same size, or are on the same point on a number line. For example, 2⁄iv is the aforementioned every bit one⁄2.

Unit fractions

Understand unit fractions – fractions with ane every bit the numerator (top number): i⁄ii, 1⁄iii, 1⁄4 – as one function of a whole when that whole is divided into equal parts.

Tip: Highlight real-life math problems

Continue to detect as many opportunities equally possible to highlight math problems in real life. If you're doubling a recipe and need to figure out measurements, enlist your third-grader's assist. Measuring cups provide an especially good opportunity for your child to familiarize herself with the concept of fractions that they are leaning about in school. If a recipe calls for a cup and a half of something, enquire them how many i⁄2 or 1⁄4 cups they would demand until they had plenty.

Tip: Highlight existent-life examples of fractions

Encourage your kid to spot real-life uses of fractions, such equally menus that describe burgers as quarter-pounders or sports games that are divided into halves. Have them practice fractions by drawing a shape, such equally a circle or a square, and request her to colour in 1⁄2 or 3⁄4 of it.

Comparison fractions

Compare 2 fractions with the same numerator (acme number) or the aforementioned denominator (bottom number) by thinking about their size, and what the summit numbers and lesser numbers represent. For case, sympathise that 3/4 of something is larger than 3/five of that aforementioned thing, because each fourth is larger than each fifth. Understand that 4/6 of something is larger than 3/vi of that same thing because it has four of the sixths.

Whole numbers

Recognize that a fraction with the same numerator and denominator is the same as ane – for example, two⁄2 = 1 (two halves are the same as i whole). Write whole numbers as fractions – for example, v⁄(1) is the same as 5.

Tell time

Reading clocks

Read circular "face" clocks and digital clocks to tell time to the nearest infinitesimal. Solve word bug requiring improver and subtraction of intervals of fourth dimension, in minutes. For example: Soccer practice is over at 4:15 p.k. Jose tells your child his mother will pick them upward and drop your child off at domicile in xx minutes. If they are on time, what time will information technology be when your child arrives?

Measurement & data

Mass and book

Measure out and approximate the mass of objects and volume of liquids – in grams (g), kilograms (kg), and liters (l).

Solve word problems involving mass and volume.

Instance:

Brian has a mass of 85 kilograms. Joe is ix kilograms lighter than Brian. What is Joe's mass?

A mug has a book of 540 milliliters. A cup has a volume of 230 milliliters. What is the total volume of the mug and the cup?

Data on graphs

Correspond and interpret data on picture graphs and bar graphs (for example one square represents v pets). Solve ane-and two- step discussion bug using information presented in bar graphs.

Shapes

Classifying shapes

Use similarities and differences in geometric shapes to categorize, or allocate them – for instance, recognize that rectangles, squares, and rhombuses all have four sides, which makes them all examples of quadrilaterals (four-sided shapes).

Dividing shapes

Divide shapes into parts with equal sizes. Chronicle the parts to fractions of the whole.
