1、 3 3 3 = 0 3 = 0 两盆一共开了几朵花？两盆一共开了几朵花？ 5 5 0 0 + + = 5 = 5 3 3 3 = 0 3 = 0 0 + 3 = 0 + 3 = 3 3 0 = 0 = 3 3 5 + 0 = 5 5 + 0 = 5 5 5 - - 5 = 5 = 5 5 0 = 0 = 3 3 0 0 5 5 0 +0 + = = - - = = 4 4 4 4 4 4 4 4 0 0 2 + 0 = 2 + 0 = 算一算。算一算。 1 1 - - 0 = 0 = 1 1 - - 1 = 1 = 3 3 - - 0 = 0 = 2 2 - - 2 = 2 = 0 + 5
2、= 0 + 5 = 2 2 1 1 0 0 3 3 0 0 5 5 说一说，填一填。说一说，填一填。 5 5 - - = = 1 1 4 4 - - = = 5 5 3 3 2 2 - - = = 5 5 5 5 0 0 4 4 4 4 4 4 0 0 2 2 2 2 2 2 0 0 3 3 3 3 3 3 0 0 算一算：算一算： 5 + 0 = 5 + 0 = 4 4 1 = 1 = 5 5 2 = 2 = 2 + 1 = 2 + 1 = 5 5 0 = 0 = 4 4 0 = 0 = 5 5 3 = 3 = 1 + 2 = 1 + 2 = 5 5 5 5 3 3 4 4 3 3 2 2 3 3 3 3 0 +0 + = = - - 0 0 = = - - = = 0 0 里可以填几？里可以填几？
