or let ss describe with sentences: what can they see on the cards? for example:

forty-seven minus twenty-two equals twenty-five.
ask more ss to practise the sentences or let them practise in pairs.
language points:
“… plus / minus… equals …”.
句中plus是介詞“加上”，也可用and代替；equal是動詞，意為“等于”，此句中也可用be動詞代替，通常把算式看作一個整體，所以 equal 和be 動詞都用單數(shù)形式。
e.g. five plus / and nine equals / is fourteen. step vi competition
