Warm-up: Mental Math Challenge
Start by giving yourself a mental math challenge. Try to solve the following problems in your head:
- 15 + 7 = ?
- 24 - 9 = ?
- 6 x 3 = ?
- 36 ÷ 4 = ?
Take your time and think through each problem. Once you have your answers, write them down on a piece of paper.

Hands-on Practice: Arithmetic Worksheets
Now, it's time to put your pencil to paper! Solve the following arithmetic problems:
- 23 + 14 = ?
- 42 - 18 = ?
- 8 x 6 = ?
- 48 ÷ 6 = ?
Use the blank paper to write down your solutions. If you need help, feel free to use a calculator.

Challenge: Word Problems
Let's apply your arithmetic skills to real-life situations! Solve the following word problems:
- Emily had 15 stickers. She gave 7 stickers to her friend. How many stickers does Emily have now?
- There are 42 students in a class. 18 students are absent today. How many students are present?
- Tom has 8 boxes, and each box contains 6 cookies. How many cookies does Tom have in total?

Write down your answers and remember to show your work!
Third Grade Talking Points
- "Arithmetic is all about working with numbers."
- "We use addition when we want to find the total of two or more numbers."
- "Subtraction helps us find the difference between two numbers or take away something from a number."
- "Multiplication is a shortcut for repeated addition. It helps us find the total when we have equal groups."
- "Division is the opposite of multiplication. It helps us share or divide things into equal groups."
- "Word problems are like puzzles that we solve using arithmetic. They help us apply math to real-life situations."
