y In an orchard there are only Cortland apple trees and Macintosh apple trees. There are a total of 168 apple trees.

• In the orchard there are 6 rows of Cortland apple trees and 8 rows of Macintosh apple trees.

• Each row in the orchard contains the same number of apple trees.

What is the total number of Cortland apple trees in the orchard? Show your work or explain how you know.

Scoring Guide

Score Description

2Student correctly answered 72 Cortland Apple Trees, with work shown or explanation given.

1

Student gives correct answer, but no work or explanation. OR Work or explanation shows correct strategy in solving the problem, but there may be a computation error.

0Response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.

Blank No response.

Sample Response:

6 + 8 = 14 rows

168 ÷ 14 = 12 apple trees in each row

6 × 12 = 72 Cortland apple trees

* All students were provided the same amount of space in which to write their answers. For the purposes of this document, extraneous white space was removed from each student work sample to save space.

Training Notes:Part a: 2 points for the correct answer, 9 (square units), with work shown or explanation given. OR 1 point for the correct answer, no work shown or explanation given. or for correct strategy shown in solving the problem, but there is a computation error.

Part b: 2 points for the correct answer, 8 (units), with work shown or explanation given. OR 1 point for the correct answer, no work shown or explanation given. or for correct strategy shown in solving the problem, but there is a computation error.

NOTES:• For part a, a student can get a strategy point for “counting squares” only if student correctly indicates the partial squares that add to 1 unit and does not use terminology such as “halves” or “quarters”. • For part b, a student can NOT get a strategy point for “counting squares”.• If student uses unit labels incorrectly (i.e. uses units of length for area or vice-versa), do not award a score of 4, otherwise do not penalize.

Sample Response:Part a: The base is 3 units and height is 6 units. The area of the rectangle is 18 square units. The triangle is half the area of the rectangle. So the triangle has an area of 9 square units.Part b: Area of the rectangle is twice the area of the triangle, so the area of the rectangle would be 40 square units. Since the base is 5 units, the height would be 8 units. or Student does it by guess and check and shows that when the height is 8 the area is 20.
