減法事實 11–18 閃卡 – 56張全彩數學卡附遊戲與活動，適合1年級以上、6歲以上，課堂或家庭學習

We've been using these for a few weeks and the focus on numbers 11-18 really helps my daughter tackle the harder facts she was stuck on. The cards are sturdy and the color coding makes it easy to sort them by difficulty.

The game ideas printed right on the cards made practice feel like play time instead of homework for my second grader. He's finally remembering the harder facts without counting on his fingers.

My son was struggling with the bigger subtraction facts, but these flashcards made practicing fun. I love that the 56 cards focus specifically on numbers 11-18, and the included game ideas keep him engaged without me having to come up with activities.
