No prior knowledge or preparation is required for this lesson.
Activities
-
Warm-up: Start by reviewing addition facts from 1 to 10. Write down the addition facts on a piece of paper and solve them one by one. For example, 1 + 1 = __, 1 + 2 = __, and so on. Take your time and try to recall the answers from memory.
-
Introduction to facts 11-20: Now, let's move on to addition facts from 11 to 20. Write down the addition facts on a new page and solve them just like in the warm-up. Take your time and try to remember the answers.
-
Practice time: Create flashcards with addition facts from 1 to 20. Write the addition problem on one side and the answer on the other side. Shuffle the flashcards and test yourself by solving them. Keep practicing until you feel confident with all the addition facts.
-
Challenge yourself: Now, let's make it more interesting. Create a timed addition fact race. Set a timer for a specific time (e.g., 1 minute) and try to solve as many addition facts as you can within that time limit. Keep track of your progress and try to beat your previous score each time you practice.

- "Addition facts are basic equations that help us quickly solve addition problems. For example, 1 + 1 = 2 is an addition fact."
- "Learning addition facts will make it easier and faster for us to solve math problems."
- "By practicing addition facts regularly, we can improve our mental math skills and become more confident in solving math problems."
