The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation.
This instructional task requires students to figure out word problems that require thinking in base 10.
Students use addition or subtraction to solve these types of word problems.
This word problem has 10 possible solutions.
In this task students determine the number of hundreds, tens and ones that are necessary to write equations when some digits are provided. Students must, in some cases, decompose hundreds to tens and tens to ones.
This task requries students to think about division by fractons.
In this task, students can see that if the price level increases and peopleŐs incomes do not increase, they arenŐt able to purchase as many goods and services; in other words, their purchasing power decreases.
This task suggests methods of introducing and continuing choral counting in the classroom.
Teachers (and then students) lead the class in chanting numbers from 1 to 120.
The purpose of this task is for students to find different pairs of numbers that sum to 7.
In this task using a number line, students must partition the interval between 0 and 1 into eighths.
The purpose of this task is to help students understand the connection between counting and cardinality. Thus, oral counting and recording the number in digit form are the most important aspects of this activity. However, teachers can extend this by making a bar graph about how many students are wearing the color each day.
The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.
This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.
The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning.
The purpose of this task is to assess studentsŐ understanding of multiplicative and additive reasoning.
The foundation of this lesson is constructing, communicating, and evaluating student-generated tables while making comparisons between three different financial plans. Students are given three different DVD rental plans and asked to analyze each one to see if they could determine when the 3 different DVD plans cost the same amount of money, if ever. (7th/8th Grade Math)
These word problems involve multiplicative comparison.
The purpose of this task is to generate a classroom discussion that helps students synthesize what they have learned about multiplication in previous grades.
The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.
