Standards-based Instruction – M.A.S.F
November 2015
S I L V I A A D A Y, D I S T R I C T I N S T R U C T I O N A L S U P E R V I S O R
Session Objectives
 Participants will review how standards-based instruction looks
in Algebra 1, Geometry, and Algebra 2.
 Participants will engage in simulations of best practices for
standards-based instruction and “look-fors” to include the
planning and its process, instructional frameworks and sample
instructional activities.
Let’s Do Some Math!
Which of the following numbers doesn't belong?
9, 16, 25, 43
Let us know what you think. And remember,
EXPLAIN YOUR REASONING!
What is Standards-based Instruction?
"Instruction involves directing students to appropriate learning
activities; guiding students to appropriate knowledge; helping
students rehearse, encode, and process information; monitoring
student performance; and providing feedback as to the
appropriateness of the student's learning activities and practice
performance.“
~Merrill, et al, 1996
Share your Thoughts!
Read each of the statements below and select which one(s) target
standard-based instruction.
Educators focus on prior teaching practices and prefer things to stay the way they are.
Instruction must remain straight to the point and narrow in understanding, unless
something forces it to change direction.
Instruction is explicitly aligned to standards to promote student achievement.
Placing emphasis on predetermined targeted goals provides guidance and support to
all stakeholders throughout the instructional process.
Standards-based Instruction
Standards-based instruction aligned to standards, includes appropriate
and meaningful activities that engage students in the learning process
and incorporates higher-order thinking skills.
It is essential to maintain alignment with the standard(s) while
planning instructional activities. Keywords identified in the
standard(s) guide educators in the instructional planning process by
bringing focus to what the student should know and be able to do.

Algebra 1
MAFS.912.F-IF.1.2
Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a
context.
MAFS.912.F-IF.1.1
Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain
exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to
the input x. The graph of f is the graph of the equation y = f(x).
MAFS.912.F-IF.2.5
Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the
function h(n) gives the number of person-hours it takes to assemble engines in a factory, then the positive integers would be an
appropriate domain for the function. ★
MAFS.912.F-IF.2.4
For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities,
and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the
function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. ★
MAFS.912.F-IF.3.9
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal
descriptions). For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger
maximum.

"Education for the future has left the harbor and is already on the
open seas. Some educators are still clinging to the belief that the
ship hasn't left and are invested in business as usual. Some
educators are enjoying the freedom of the open seas ... excited
about the foreign ports and places they will visit.“
