What in the world is DeltaMath aka DM?
Making Assignments the modern way!
Other Important Stuff
Online math program
Students do problems....
Modern way to do hw!
Created by a previous MfA cohort member!
When rationalizing fractions
or simplifying radicals, there
is always a radical symbol and
a denominator provided in the
answer form, even if it is
Student Confusions
When solving different
kinds of equations,
students are often
presented with the
option to enter
multiple solutions, even if
there is only one.
Students are marked incorrect if they enter "X" rather than "x" for their solutions.

When factoring polynomials, students may be marked incorrect based on the order that they write the factors, even if they are correct.
Teacher Complaints
If you have more than one class on Delta Math, the student data page initially displays each class, along with all of the assignments for each class.

In order to look at just one class, you need to scroll through the classes.
(First World Problems)
Delta Math often uses formulas and notation that the teacher does not use.
Delta Math may or may not display student
names alphabetically, depending on which
browser you use.

Fire Fox does display names alphabetically,
but Google Chrome does not.

Access Graphing Calculator
Go to http://www.deltamath.com/graphingcalc.html
You can only have two functions on this calculator!
There is an apparent glitch when students are asked to draw a graph*. You need at least two points for a line, but the calculator sometimes doesn't process that students have, in fact, plotted two points. In frustration, they keep choosing points, and then receive an error message that they have too many points.

Helping Students Learn
A.CED.A.1: Create equations and inequalities in one variable and use them to solve problems.
A.CED.A.2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
G.SRT.B.4: Prove theorems about triangles.
F.TF.B.5: Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline
