C)Counts out sixteen and makes two piles of eight and tells you there are sixteen.
D)Counts out sixteen and places 6 aside and tells you 10 and 6 are sixteen.

Answer 2

Counts out sixteen objects and can tell you how many by counting each piece.

Question 3

The mathematical language we use when introducing base-ten words is important to the development of the ideas.Identify the statement that consistently connects to the standard approach.

B)Models like abacus are hard to learn how to use.
C)Models like money provide more conceptual than procedural knowledge.
D)Models do not engage the students as much as the proportional models.

Question 10

What would be a strong indication that students are ready to begin place-value grouping activities?

A)Students understand counting by ones.
B)Students have had time to experiment with showing amounts in groups of twos,fives and agree that ten is a useful-sized group to use.
C)Students have only worked with small items that can easily be bundled together.
D)Students are able to verbalize the amounts they are grouping.

Question 11

The statement below are all helpful when guiding students to conceptualize numbers with 4 or more digits EXCEPT;

A)Students should be able to generalize the idea that 10 in any one position of the number result in one single thing in the next bigger place.
B)Because these numbers are so large,teachers should just use the examples provided in the mathematics textbook.
C)Models of the unit cubes can still be used.
D)Students should be given the opportunity to work with hands-on,real-life examples of them.

Question 12

What is the major challenge for students when learning about three-digit numbers?

A)Students are not clear on reading a number with an internal zero in place.
B)A different process is used than how students learned with two-digit numbers.
C)Students are not competent with two-digit number names.
D)An instructional process that values quick recall and response.

Question 13

The multiplicative structure of a number would help students in acquiring skill in all of the following EXCEPT:

A)Writing numbers greater than 100.
B)Reading large numbers.
C)Knowing ten in any position means a single thing.
D)Generalizing structure of number system.

Question 14

What mathematical representation would help students identify patterns and number relationships?

A)Blank number line.
B)Hundreds chart.
C)Place value chart.
D)10 x 10 Multiplication Array.

A)Using arrays to cover up rows and columns and ask students to identify the number name.
B)Lie out base-ten models and ask students to tell you how many tens and ones.
C)A chain of paper links is shown and students are asked to estimate how many tens and ones.
D)Students need to show with fingers how to construct a named number.

Question 16

What is the valuable feature of what hundred charts and ten-frame cards demonstrate?

A)The meaning behind the individual digits.
B)The identity of the digit in the ones place and in the tens place.
C)The distance to the next multiple of ten.
