Materials and Prep
- Pen or pencil
- Mathematics worksheet
No prior knowledge is required for this lesson.
Activities
- Start by warming up your math skills with a quick mental math exercise. Solve the following problems in your head: 15 + 7, 25 - 9, 6 x 3, and 48 ÷ 6. Write down your answers.
- Complete the provided mathematics worksheet. It contains a variety of arithmetic problems involving addition, subtraction, multiplication, and division. Take your time and solve each problem carefully. If you get stuck, don't hesitate to ask for help.
- Once you have finished the worksheet, check your answers. Use a different color pen or pencil to mark your correct and incorrect answers. If you made any mistakes, try to understand where you went wrong and correct them.
- Challenge yourself by creating your own arithmetic problems. Write down at least three addition, subtraction, multiplication, and division problems. Solve them and check your answers. You can even create a math quiz for a family member or friend to solve!
Third Grade Talking Points
- "Arithmetic is a branch of mathematics that deals with numbers and the basic operations we can perform on them."
- "Addition is the operation of combining two or more numbers to find their total or sum. For example, if we have 3 apples and we add 2 more apples, we will have a total of 5 apples."
- "Subtraction is the operation of taking away one number from another to find the difference. For instance, if we have 7 cookies and we eat 3 cookies, we will be left with 4 cookies."
- "Multiplication is the operation of repeated addition. It helps us find the total when we have equal groups of the same number. For example, if we have 4 bags, and each bag contains 6 marbles, we can find the total number of marbles by multiplying 4 by 6, which gives us 24 marbles."
- "Division is the operation of sharing or dividing a number into equal parts. It helps us find out how many groups we can make or how many are in each group. For instance, if we have 12 candies and we want to share them equally among 3 friends, each friend will get 4 candies."
