Balance addition equations - up to two digits
Balance addition equations - up to two digits
What you'll learn
- Identify if an addition equation with a missing number is balanced or not (e.g., 5 + 3 = 6 + ?).
- Solve for the missing number in an addition equation with one unknown to make it balanced, using numbers up to 20 (e.g., 4 + ? = 6 + 2).
- Explain, using pictures or numbers, how to find the missing number in a balanced addition equation (e.g., explaining why 3 + 5 = 4 + 4 is balanced).
- Apply knowledge of addition facts to determine the missing number in a balanced equation up to two digits (e.g., 12 + 5 = 10 + ?).
