The purpose of this task is for students to show they understand the connection between fraction and decimal notation by writing the same numbers both ways.
The purpose of this task is to provide students with an opportunity to explain fraction equivalence through visual models in a particular example.
An online, interactive, multimedia math investigation. The Factor Game engages students in a friendly contest in which winning strategies involve distinguishing between numbers with many factors and numbers with few factors. Students are then guided through an analysis of game strategies and introduced to the definitions of prime and composite numbers.
This task allows students to relate addition and subtraction problems to money in a context that introduces the concept of scarcity.
This task asks students to locate fractions on a number line.
This simple-looking problem reveals much about how well students understand unit fractions as well as representing fractions on a number line.
This task asks students to find and use two different common denominators to add the given fractions. The purpose of this question is to help students realize that they can use any common denominator to find a solution, not just the least common denominator.
This task asks students to use two different denominators to subtract fractions. The purpose of this is to help students realize that any common denominator will work, not just the least common denominator.
These word problems require students to compare contexts for addition and subtraction.
This task asks students to solve addition and subtraction equations with different structures so that they are able to see the connections between addition and subtraction more easily.
The purpose of this task is to provide students with a concrete experience they can relate to fraction multiplication. Perhaps more importantly, the task also purposefully relates length and locations of points on a number line, a common trouble spot for students. This task is meant for instruction and would be a useful as part of an introductory unit on fraction multiplication.
Using this tool, students build these classic fractals: the Koch snowflake, a fractal tree, a reduced square, and the Sierpinksi triangle. As these shapes grow and change using an iterative process, students can observe patterns in the images created and in the table of values as the fractals progress through several stages.
In this task students are asked to explain fraction equivalence.
This applet allows students to individually practice working with relationships among fractions and ways of combining fractions. It is an online, one person game, with immediate feedback on incorrect moves. All instructions for this fun visual game are included and illustrated.
Explore different representations for fractions. This applet allows students to create a fraction,then see it as a visual model, and as percent and decimal equivalents. They can choose the model to be a circle, a rectangle, or a set model. Intended for the young learner, this version restricts the numerator to values from 0 to 20, and the denominator to benchmark values of 1, 2, 4, 5, 8, 10 and 20.
I use this to help students understand that fractions are numbers to make sense of, just like whole numbers. The activity also focuses on understanding the main parts of a fraction, the numerator and the denominator.
This task requires students to think about and compare fractions.
The first of these word problems is a multiplication problem involving equal-sized groups. The next two reflect the two related division problems, namely, "How many groups?" and "How many in each group?"
In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 (1.OA.6). They are presented with opportunities intended to advance them from counting all to counting on, which leads to decomposing and composing addends and total amounts.
Analyze and describe embedded numbers (to 10) using 5-groups and number bonds.
