LEVEL 12
Level 12 helps students to develop into algebraic thinkers with practice with equations, including
fractions, decimals, exponents, as well as beginning work with the concept of functions. Students
also increase their facility with decimals by rounding, truncating, and comparing decimals.

Sublevel 12.1
This level begins by challenging students to increase their skill in solving algebraic equations (with
one variable) to include equations that contain fractions and decimals.

Sublevel 12.2
At this sublevel, students can advance their decimal skills with practice with rounding, truncating,
and comparing decimals.

Sublevel 12.3
Review and reinforcement of concepts covered in previous sections.

Sublevel 12.4
Students are now asked to develop their algebraic skills by solving one-variable equations involving
exponents.

Sublevel 12.5
Here, students start to increase their abstract algebraic thinking by working with the concept of
functions. They practice by substituting in for the variables in equations using the function format.

Final Review & Test
Students will review all the skills covered at this level. After the review process, there will be a
final test to make sure conceptual understanding is developing properly, before moving ahead.
