equation. For each number that can be obtained, the corresponding circle is shaded. (This indicates a pin knocked down.)
Student assessment activity: After explaining the rules of Bowl-A-Fact, the teacher should play one game with the whole class. Pretend that the number cubes on the first toss were 3, 4, and 6. Individual students can devise number sentences to knock down pins that have been drawn on the board, as shown below.
Of course the pins will probably be knocked down in some order different from the one shown. Also, depending on a child's strategy, the pin number could be on the right or left side of the equals sign. For example, one child might ask, "What can I do with 3, 4 and 6?" and come up with "4 + 6-3 = 7," while another might ask, "Is there any way to knock down the 7 pin?" and write the equation "7 = 4 + 6-3.''
Note, too, that there are other ways of getting many of the pin numbers; this should be explicitly pointed out.
