Самостоятельная работа."Состав числа 9.Смысл действия умножения."(21 век.1 кл.)

9	0		3		5		2		4
		7		8		9		1		6
9 = 7 +   ...                              ... + 4 = 9                          6 ... 3 = 9 9 = 5 +  ...                               ... + 8 = 9                          10 ...1=9

9 = ... +  6                               9 + ... = 9                          9 ...1 =10

9 ... 10                                     20 ...9                                9 ... 9

9 ...1                                         0 ...9                                  9 ... 19

Составить тройку примеров к примеру:

7+ 2 =9                                    3 + 6 = 9

2 + ...=9                                   6 + ...= 9

9 - ... =                                     9 - ...=

9 - ...=                                      9 - ...=

Заменить на сложение:

7х 3 =

9 х 2=

Заменить на умножение:

6 + 6 + 6 =

9 + 9 + 9 + 9 + 9 =
