SEAGReady breaks addition facts to 20 into 2 steps, taught in order so each skill builds on the last.

Recall addition facts where the sum is between 11 and 20 (e.g., 8 + 5 = 13)
Three free sample questions from our addition facts to 20 course. Every question comes with a full explanation, and hints that guide without giving the answer away.

Sean has 7 football stickers. His friend gives him 6 more stickers. How many stickers does Sean have now?
Answer: B. 13 stickers
