# Gr 5_NBT_DecimalsOrdering_Problem_Critique_BattingOrders

Batting Orders is a task designed for fifth graders developing skills with decimals. Students must critique a student response that has to order three decimals from least to greatest. The decimals all go to thousandths place value. Students must be able to compare the decimals and order them. The task uses argumentation language by asking students to state a claim and consider warrants.

# Gr 5_NBT_DecimalsRounding_Problem_Critique_DifferentIdeas

Different Ideas is a problem designed for fifth-grade students to understand rounding decimals to the nearest hundredth. Two responses are given as to what a decimal rounded to the nearest hundredth is and students are to critique the response and choose a side. The task uses argumentation language when specifically asking for the claim and evidence.

Ordering Decimals with Zero Digits is a family of tasks on decimals to help fifth graders understand if decimals with more zero digits are greater than those without zero digits. In the first example given, the zeros are in the hundredths and thousandths place values, and the decimals to be ordered have the same number in the tenths place. In the second example, the ones, tenths, and hundredths place values are the same, while the zeros lie in the thousandths and ten-thousandths place. Both examples provide multiple variations and extensions to enforce stronger critiques of the given responses and to contain argumentation language.

# Gr 5_NBT_DecimalsEquivalence_Problem_Critique

This task is designed for fifth graders and uses a visual picture of a 100% block. It asks students to critique two student responses that state how much of the block is shaded. Each student takes a different approach, but essentially states equivalent answers. One student looks at all of the pieces individually, as 23 ones, and the other student looks at the pieces like place values, as 2 tens and 3 ones. Students must recognize that these are two different ways to arrive at the same answer. Students are asked to draw pictures and use words to explain how the two students came about the answer in different ways.This task is an excellent example of how students may use different interpretations and methods to solve the same problem.

Dividing by a Decimal is a family of tasks on decimals to help fifth graders understand decimal division. Students are given a statement where a whole number is divided by a decimal and are to critique the provided answer. Different variations of the question are provided with scaffolding and argumentation language to promote stronger critiques of the response that include a claim and evidence.

# Gr 4_NBT_Multiplication_ThinkPairShare_Critique_Statement

This multi-digit multiplication task was used with fourth-grade students. Students are asked to critique a statement on if two numbers multiplied together are equal to two numbers added together. After an initial conjecture, students share their ideas with a partner and identify similarities and differences between the two arguments. This task contains argumentative language, including claim and evidence.

# Gr 4_NBT_Multiplication_ThinkPairShare_Critique

This task is designed as a think-pair-share. It sets a multiplication expression equal to an addition expression and asks students to agree or disagree about the equality. Fourth grade students are given a template to state a claim, and explain it, then compare arguments. This task can be used to open a class discussion about different ways to think about double digit multiplication. Students can look at 10×24 as (10×20)+(10×4) which would show the comparison between 10×24 and 200+40 nicely.
