Самостоятельная работа."Состав числа 8.Смысл действия умножения."(21 век.1 кл.)

8	0		3		2		8		4
		6		5		7		1

8 = 7 + ...                       ... + 1 = 8                                     6 ... 2 =8

8 = 5 + ...                       ... + 4 = 8                                     3 ... 5 =8

8 =... + 2                        6 + ... =8                                      8 ... 2 =10

8 = ...+ 3                        8 + ... =8                                      8 ... 2 = 6

8 ... 18                            8  ... 20                                         8 ... 8

10 ... 8                            8 ... 1                                             0 ... 8

Составить  тройку примеров  к примеру:

3 + 5 = 8                                      7 + 1 = 8

5 + ... =8                                   1 + … = 8

8 - ... =                                          8 - ... =

8 - ... =                                          8 - ... =

Заменить на сложение:

8 х 2 =

2 х 4 =

Заменить на умножение:

2+2+2=                                                       3+3+3+3+3=
