Use place value understanding and properties of operations to
perform multi-digit arithmetic.
1. Use place value understanding to round whole numbers to the nearest
10 or 100.
2. Fluently add and subtract within 1000 using strategies and algorithms
based on place value, properties of operations, and/or the relationship
3. Multiply one-digit whole numbers by multiples of 10 in the range
10-90 (e.g., 9 x 80, 5 x 60) using strategies on place and properties of
operations..
Cognitive Rigor and Depth of Knowledge
•
The level of complexity of the cognitive demand.
– Level 1: Recall and Reproduction
• Requires eliciting information such as a fact, definition, term,
or a simple procedure, as well as performing a simple algorithm
or applying a formula.
– Level 2: Basic Skills and Concepts
• Requires the engagement of some mental processing beyond
a recall of information.
– Level 3: Strategic Thinking and Reasoning
• Requires reasoning, planning, using evidence, and explanations
of thinking.
– Level 4: Extended Thinking
• Requires complex reasoning, planning, developing, and
thinking most likely over an extended period of time.
Level 1 Example
Select all of the expressions that have a value between 0 and 1.

Level 2 Example
A cylindrical tank has a height of 10 feet and
a radius of 4 feet. Jane fills this tank with water
at a rate of 8 cubic feet per minute. How many
minutes will it take Jane to completely fill the
tank without overflowing at this rate?
Level 3 Example
The total cost for an order of shirts from a company consists of the cost for
each shirt plus a one-time design fee. The cost for each shirt is the same
no matter how many shirts are ordered.
The company provides the following examples to customers to help them
estimate the total cost for an order of shirts.
• 50 shirts cost \$349.50
• 500 shirts cost \$2370
Part A: Using the examples provided, what is the cost for each shirt, not
Part B: What is the cost of the one-time design fee? Explain how you found
Level 4 Example
During the task, the student assumes the role of an architect
who is responsible for designing the best plan for a park with
area and financial restraints. The student completes tasks in
which he/she compares the costs of different bids, determines
what facilities should be given priority in the park, and then
develops a scale drawing of the best design for the park and an
explanation of the choices made. This investigation is done in
class using a calculator, an applet to construct the scale drawing,

Claim 1
Concepts and Procedures
Operations and Algebraic Thinking
Target A [m]: Use the four operations with whole numbers to solve problems. (DOK 1, 2)
Tasks for this target will require students to use the four operations to solve straightforward,
one-step contextual word problems in situations involving equal groups, arrays, and finding
an unknown number, including problems where the remainder must be interpreted. Some of
these tasks will draw on contexts in 4.MD Target I using measurement quantities such as time,
liquid volume, and masses/weights of objects, and money (with decimal representations
limited to those described in standards 4.NF.6 and 4.NF.7).
