A function is a rule which maps a number to another unique number. In other words, if we start off with an input, and we apply the function, we get an output. For example, we might have a function that added 3 to any number. So if we apply this function to the number 2, we get the number 5.
Students are given "input" and "output" numbers and write the rule being used to produce the answer (e.g. "Subtract 6" or "Multiply by 3"). Worksheets cover all 4 operations, and equations are based on standard math facts.
Symbol and Cue Cards. Create a set of symbol cards and matching cue cards as shown on the following pages. Symbol cards: Cards containing math terms, expressions, equations, etc. Cue cards: Cards containing phrases that match one or more of the symbol cards.
Stahl and Fairbanks (1986) recommend that students be exposed to words at least seven times over spaced intervals for retention to occur. Summary • Vocabulary is an essential element of solving word problems. • In mathematics, what might be thought of as Tier One words can prove to be tricky. Consider the use of the words, ‘and’ and ...
Input Output Tables Worksheets. We have split these worksheets into 5 different sections across two webpages. The first section is the easiest with single operation rules and questions involving finding the missing outputs and inputs. They are aimed at 3rd and 4th graders.
Define, evaluate, and compare functions. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
This section will show you how to: understand and use the terms: function, domain, range (image set), function and composition of functions. use the notation f( x ) = 2 x 3 + 5 , f : x ↦ 5 x − 3 , f − 1 ( x ) and f 2 ( x ) understand the relationship between y = f( x ) and y = |f( x )|.
