Developing Meanings for the Operations

This activity contains 11 questions.

	The category of problems where the initial amount is the whole or largest value is called   Separate Compare Join Part-part-whole

	The computational equation for the equation 3 + 7 = 10 looks like   _____ + ______ = 10 10 -- 7 = _________ _________ + 7 = 10 3 + _________ = 10

	Counting the number of pairings you can make between two sets is a model of   Equal groups Combinations Multiplicative comparison Product of measures

	The multiplication property that explains a x ( b + c) = a X b + a X c is   Order property Commutative property Distributive property Associative property

	Which of the following statements is true?   Part-part-whole problems involve two parts that are combined into one whole. In the separate problems, the largest amount is the unknown. Compare problems involve the comparison of the whole to a part. For join problems, the initial, change, and resulting amount are unknown.

	Change problems are most difficult when the initial value is unknown.    True  False

	Number line problems are a good model to teach addition to first and second graders.    True  False

	Multiplicative comparisons and equal groups are the most prevalent class of multiplicative structures in elementary school.    True  False

	Kindergarten and first graders are not capable of solving multiplication and division problems especially division with remainders.    True  False

	Students should just think of remainders as "left over" amounts.    True  False

	Given the problem of 3 x 4, describe at least 2 models for showing the solution.   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.
