# Gr 4_OA_Multiplication_ArgumentFrame_Construct

Fourth graders are given this word problem to understand multiplication, though division can be used. This task is formatted as a graphic organizer, with a space for the problem, mathematical practice and vocabulary, claim, evidence, and warrants. Students are to use the graphic organizer to formulate their thoughts and construct an argument to complete the problem.

# Gr 3_OA_SubtractionMultiDigitAlgorithm_Problem_Critique_1

I used this task with my 3rd grade students. The purpose of this task was to notice how to use regrouping when subtracting. I wanted students to recognize and understand when it is appropriate to regroup when subtracting. The students were given 2 different answers for the same subtraction problem. The student had to decide which answer was correct. The student had a place to include their claim and argument, as well as have time to discuss with a partner and record their partner’s thoughts.

This task is a set of addition and subtraction word problems with three follow up questions created for third graders. Double-digits are used in the word problems and students must decide for themselves when to use addition or subtraction through the construction of the responses. The follow up questions contain argumentative language and ask students to describe how they solved the problem, the warrants behind it, and a claim and evidence pertaining to a partner’s strategy.

This task is geared towards third graders. The task states a problem asking for the difference between two quantities and asks students to crititque two statements about the problem: Is finding the difference an addition or subtraction problem? Students are provided space to think about the problem, make a claim, and provide evidence. This task could start a class discussion about how students might think differently about subtraction problems. Some students may state that this is subtraction because one can subtract the two quantities to find a difference while other students may look at this as an addition problem by looking at how much must be added to one quantity to get to the next.

This think-pair-share task is provided for third-grade students to understand the commutative property for addition. Using a statement with single-digit numbers, students must construct an argument on whether the true statement is correct and share their ideas with a partner. A graphic organizer is provided to help students create their claim and evidence, as well as record their partner’s ideas and any similarities/differences.

# Gr 3_OA_MultiplicationSingleDigit_Problem_Critique

This task is designed for third grade studenrs learning applications of single digit multiplication. Students are given an application along with a student response and asked to critique the student response. The task uses argumentation language by first asking students to solve the problem, then having students state a claim and provide evidence to support the claim. The task provides space for each piece of the argument.

# Gr 3_OA_MultiplicationSingleDigit_Problem_Critique_ArtSupplies

In Art Supplies, third graders are given a single-digit multiplication word problem. Students must critique the two given responses, which address the misconception that the number of boxes and the amount in each box should be added together and not multiplied. A graphic organizer is provided and contains argumentative language to help students create their claim and provide evidence and warrants.

# Gr 3_OA_MultiplicationSingleDigit_Problem_Construct_IceCreamSundaes

Ice Cream Sundaes is geared towards third graders developing multiplication skills. This task asks students to find the total number of possible combinations of two separate entities. Students must construct an argument and are given space to provide work and space to explain thinking. This problem can open the class to conversations about methods to solve the problem because students can do the math (single digit multiplication), draw pictures, or create a diagram.

# Gr 3_OA_MultiplicationPropertyCommutative_Problem_Construct_SameOrDifferent

Third graders are developing an understanding of the commutative property through single-digit multiplication in Same of Different?. Students are asked if two rectangles are the same given reverse length and width measurements. Argumentation language is present when asking students to explain their thinking using claim, evidence, and warrants.
