This flawed reasoning task addresses misconceptions with determining area.
This task requires students to find the area and perimeter of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d, 3.MD.D.8, and 3.OA.D.8.
This task requires students to find the area of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d and 3.OA.D.8.
This task requires students to find the area of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d and 3.OA.D.8.
This is a concrete referent reasoning task for Grade 3. Students need to use the diagram to find the information to find the area of a rectilinear figure. This is a task that would be a good starting point for solving problems for this standard.
A task related to standard 3.MD.7d, additive area of rectilinear figures. Students find the area of the parts of a pool to ultimately find the area of the entire pool.
This task gives students the opportunity to analyze two number lines in order to identify the one that correctly shows an improper fraction. Students then communicate their understanding by describing the reasoning they used to determine their answer was correct. It is aligned to evidence statement 3.C.6-1
This number line task has students reason about which fractional distance is farther.
This task gives students the opportunity to reason about equivalent fractions. Students use images to develop an accurate claim and describe their thinking through reasoning.
A math task on Sub Claim C: Concrete Referents. Students are using a provided image to compare fractions of the same sized whole and then compare. Students explain how they know which fraction is the greatest.
This task provides students practice with flawed reasoning using fraction comparisons.
This flawed reasoning task provides practice for students to understand the size of the wholes must be equal in order to compare fractions.
This task is focused on Common Core Standards 3.OA.3 Students are applying understanding of multiplication concepts to solve a multi-step word problem related to a real life context. This is a good beginning task to help students show all their work using equations to represent the solution path for the task. It also helps students focus on precision as they need to represent the problem with the correct equations.
This task provides practice with flawed reasoning with the distributive property.
This task provides students the opportunity to identify a mistake in reasoning related to the relationship between multiplication and division.
