All Grades TAKS Math Charts

No matter what grade you are in, check out each Math chart, starting with 3rd grade. As you will see, each year the chart grows and with that the expectation that each previous year's formulas are added to new concepts that will be tested on for that year's test. As a teacher, I've found that the students are not spending enough time using the chart and therefore don't value using it during the actual test. If you're in middle school, take a look at the high school chart. When you get to high school, please know that you'll be expected to know all middle school TAKS Math concepts from the 8th grade chart, which take care of 3rd-8th Math concepts.

History of the TAKS Test

History of TAKS Development

In 1999 the 76th Session of the Texas Legislature enacted Senate Bill 103, mandating implementation of a new statewide testing program. The new testing requirements, subsequently named the Texas Assessment of Knowledge and Skills, were implemented in spring 2003. By law, all eligible Texas public school students are assessed in mathematics in grades 3–10 and exit level; reading in grades 3–9; writing in grades 4 and 7; English language arts in grades 10 and exit level; science in grades 5, 8, 10, and exit level; and social studies in grades 8, 10, and exit level. Eligible students may meet testing requirements with Spanish versions of the TAKS assessments, available in mathematics at grades 3–6, in reading at grades 3–6, in writing at grade 4, and in science at grade 5.

8th Math TEKS from TEA

(a) Introduction.
(1) Within a well-balanced mathematics curriculum, the primary focal points at Grade 8 are using
basic principles of algebra to analyze and represent both proportional and non-proportional
linear relationships and using probability to describe data and make predictions.
(2) Throughout mathematics in Grades 6-8, students build a foundation of basic understandings in
number, operation, and quantitative reasoning; patterns, relationships, and algebraic thinking;
geometry and spatial reasoning; measurement; and probability and statistics. Students use
concepts, algorithms, and properties of rational numbers to explore mathematical relationships
and to describe increasingly complex situations. Students use algebraic thinking to describe
how a change in one quantity in a relationship results in a change in the other; and they connect
verbal, numeric, graphic, and symbolic representations of relationships. Students use geometric
properties and relationships, as well as spatial reasoning, to model and analyze situations and
solve problems. Students communicate information about geometric figures or situations by
quantifying attributes, generalize procedures from measurement experiences, and use the
procedures to solve problems. Students use appropriate statistics, representations of data,
reasoning, and concepts of probability to draw conclusions, evaluate arguments, and make
recommendations.
The provisions of this subchapter were adopted by the State Board of Education in February 2005 to be implemented beginning
with the 2006-2007 school year.
10
(3) Problem solving in meaningful contexts, language and communication, connections within and
outside mathematics, and formal and informal reasoning underlie all content areas in
mathematics. Throughout mathematics in Grades 6-8, students use these processes together with
graphing technology and other mathematical tools such as manipulative materials to develop
conceptual understanding and solve problems as they do mathematics.

(A) predict, find, and justify solutions to
application problems using
appropriate tables, graphs, and
algebraic equations; and
(B) find and evaluate an algebraic
expression to determine any term in
an arithmetic sequence (with a
constant rate of change).
(8.6) Geometry and spatial reasoning.
The student uses transformational
geometry to develop spatial sense.
The student is expected to:
(A) generate similar figures using
dilations including enlargements and
reductions; and
(B) graph dilations, reflections, and

such as art and architecture;
(C) use pictures or models to demonstrate
the Pythagorean Theorem; and
(D) locate and name points on a
coordinate plane using ordered pairs
of rational numbers.
(8.8) Measurement. The student uses
procedures to determine measures of
three-dimensional figures.
The student is expected to:
(A) find lateral and total surface area of
prisms, pyramids, and cylinders using
concrete models and nets (twodimensional
models);
(B) connect models of prisms, cylinders,
pyramids, spheres, and cones to
formulas for volume of these objects;
and
(C) estimate measurements and use

similar three-dimensional figures to
find missing measurements.
(8.10) Measurement. The student describes
how changes in dimensions affect
linear, area, and volume measures.
The student is expected to:
(A) describe the resulting effects on
perimeter and area when dimensions
of a shape are changed
proportionally; and
(B) describe the resulting effect on
volume when dimensions of a solid
are changed proportionally.
(8.11) Probability and statistics. The
student applies concepts of
theoretical and experimental
probability to make predictions.

Constructing Pie/Circle Graphs 7.11A

Yesterday my classes all took a survey of their favorite classes. Each student chose only one subject as their favorite. The end result was the class as a whole constructing their own pie chart, breaking down the totals, turning them into fractions, decimals, percents, and finally degrees, so the pie could be cut into parts according to the angles. Quite a few TEKS were covered and the students were all engaged. I plan on continuing surveys throughout the year so I can spiral this lesson.

Below is an example of tracking from one of my blogs. The information gathered was about returning visitors. From this information you can easily calculate the degrees of each angle for the percent and number of each category is already given.
