一、填一填1 你能写出别的算式来吗?(1)4 +4 +4 +3=(2)6 +6 +6 +6 -5=(3)3 +3 +3 +3 +3 +3 +4 +5=2.在□里填上适当的数 ,想想有几种填法。(1)2×□=4×□(2)9÷9=□÷□(3)□×6 -□=6(4)(6 -□)×□=6这是在学习表内乘除法后 ,我设计的策略性开放练习题。这种填空题看起来平?
First, fill in a fill 1 can you write other formulas come? (1) 4 +4 +4 +3 = (2) 6 +6 +6 +6 -5 = (3) 3 +3 +3 +3 +3 +3 +4 +5 = 2. Fill in the appropriate number of □, think of several ways to fill. (1) 2 × □ = 4 × □ 9 ÷ 9 = □ ÷ □ (3) □ × 6 - □ = 6 (4) (6 - □) × □ = 6 This is the multiplication and division in the learning table After that, I designed a strategic open exercise. This blank filling problem seems flat?
