This is a harder version of concentration -- matching pictures from a set of 10-15 or 20 of the 40 flower pictures. It is harder because the flowers selected are not as familiar as those in Vol. 1 and 2. There is an Identification Chart to help students recognize the flowers. There is also a chart comparing dicots and monocots.
There are many nature study and science games in my TPT store -- Crosswords, Word Search, Bingo, Rummy, Concentration, Sorting, Tic Tac Know, Dominoes and Board games.
