This flawed reasoning task addresses misconceptions with determining area.
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 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
Fraction_Number_Lines.JPGTwo number lines are shown. The first number line shows the numbers 0 through 3 and is partitioned into 6 equal parts in each whole.
The second number line shows the numbers 0 through 3 and is partitioned into 8 equal parts in each whole.
one_half.PNGThis image shows a number line with the intervals zero through four marked. One-half is marked between the zero and one.
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.
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.
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.
