  / \                                   / \                                   / \                                       / \

 

2. Розклади числа за зразком . Розв’яжи.

 

400 – 50 = (300 + 100) – 50 = 300 +(100 – 50) = _____

700 – 80 = (600 + 100) – 80 = 600 + (100 – 80 )=_____

500 – 60 = _____________________________________     

300 –20 =______________________________________

800 – 70 = _____________________________________            

 

 

3. Розв'яжи самостійно.

 

500 – 30 =            300 - 60 =                 900 – 40 =                600  - 20 =            300 – 60 =    

600 – 40 =          

 

800 - 90 =                 200 – 40  =               900  - 80=             400  - 70 =      

700 – 80 =            900 - 40 =                 

 

 

 

 

 

 

 

 

400 – 20 =                           700 – 80 =            900 – 60 =                             500 – 50 =                                      900 – 70 =                              800 – 70 =              

 

600 – 60 =            700 – 40 =                                                 900 – 20 =                           

400 – 20 =                             700 – 90 =                            300 –  40 =
