20以內加減法
坐上火箭,飛向正確的星球!這個遊戲混合20以內加減法,訓練運算流暢度(fluency)— 還有一個常被忽略的好習慣:答題之前先看清楚是「+」還是「-」。小一測驗最常見的大意失分,就是看錯符號,而不是不會計算。
Board the rocket and fly to the correct planet! This game mixes addition and subtraction within 20 to build fluency — plus one often-overlooked habit: check whether the sign is "+" or "−" before answering. The most common careless mistake in Primary One tests is misreading the operator, not miscalculating.
提醒小朋友「先看符號,再計算」。答錯時不要即時報答案,問他:「這題是加還是減?」讓他自己發現。流暢度靠少量多次:每天5分鐘,好過週末做一次長練習。
Remind your child: "sign first, then solve." When they slip, don't hand over the answer — ask: "Was that add or subtract?" and let them spot it themselves. Fluency comes from little and often: five minutes daily beats one long weekend session.
自製口算卡每天抽5題;玩飛行棋時請小朋友自己數步數、算「還要走多少步才到終點」— 全部都是加減混合的生活版本。
Make flashcards and draw five a day; when playing board games, ask your child to count the steps and work out "how many more to the finish?" — everyday versions of mixed addition and subtraction.
