One standard requires students to represent a number of objects with a written numeral.
The Concentration Game requires students to match each quantity with the correct symbol.
Two digit numbers between 13 and 50 are use.

Another standard requires students to count from a given number instead of starting at the number one
This standard would be affected by the count all strategy used sometimes when the
minimum count strategy is more efficient.
The downhill snowboarding game, Sums to Ten, would help them learn
to start at a number other than one
and use the count minimum strategy when adding two numbers.

Another standard requires that students identify whether the number of objects in one group
is greater than, less than, or equal to the number of objects in another group.
They must also compare two numbers presented as written numerals.
The Paddle Ball game requires the player to identify numbers
greater than, equal to or less than five.
The Football Passing Practice Game requires students
to compare written numbers and numbers as sets of dots.

Another standard involves solving word problems with combinations of coins.
Money involves the issue of physical size versus value, and it is potentially an important daily event.
Studies have been made on the effect of physical size versus value such as stating which is bigger 4 or 5
when the 4 is in a bigger font versus when the 5 is in the bigger font.
A nickel is bigger than a dime but has a smaller value.
Even when combined with two pennies these three coins have a smaller value than the dime.
The concentration game uses sets of three coins and the space debris game uses sets of two coins.

Students must also understand subtraction as taking apart and taking from.
The Journey to Mars game has the player remove a certain number
from 10 items and then say how many items are left.

There are many standards that involve fractions which have their unique issues.
As the denominator gets larger the amount gets smaller (1/3 is less than 1/2).
Also when counting the pieces to name the fractions some of the pieces are counted twice.
Given all of the research and potential benefits regarding number lines
all of the fractions are shown in a linear format instead of as squares.

The Concentration Game requires students to match each quantity with the correct symbol.
One standard requires students to understand a fraction as a number on the number line.
The number line puzzle has students construct the number line for fractions up to 1/8.

The RPS snowboarding game requires students to match each quantity with the correct nonsymbolic image.
This game utilizes the part of the brain that reacts to ratios.
Specific neurons in this region will react to specific ratios such as 1/3 or 3/4.
This newly identified area is an area upon which fractional understanding can be built.

Another standard requires that students compare two
fractions with the same numerator or the
same denominator by reasoning about their size.
The Football Passing Practice Game requires students
to compare two fractions with the same numerator.

The RPS Football Passing Practice Game requires students to compare fractions using nonsymbolic images.
This game utilizes the part of the brain that reacts to ratios.
Specific neurons in this region will react to specific ratios such as 1/3 or 3/4.
This newly identified area is an area upon which fractional understanding can be built.

Level one of the space debris game also requires students to compare fractions.
They must hit the objects in order from small to large.
All of the fractions have a numberator of one.

The RPS space debris game also requires students to compare fractions using nonsymbolic images.
This game utilizes the part of the brain that reacts to ratios.
Specific neurons in this region will react to specific ratios such as 1/3 or 3/4.
This newly identified area is an area upon which fractional understanding can be built.
