## Benchmark Numbers: Everyone Can ‘DO’ Fractions, Decimals and Percents!

**How do your students generally feel about fractions? decimals? percentages? ***Do they moan and groan and say “I hate these” or “I can’t DO… (fractions, decimals, percents)”*

**How about yourself? How much do you enjoy computations and problem solving involving fractions, decimals and percentages?**

A common challenge for many of our learners is their ability to work with a particular set of number concepts: **fractions**, **decimals**, and **percents**. Our learners have often developed ‘mental blocks’ to these mathematical concepts and even develop anxiety upon hearing the terms. Yet anyone entering an adult education classroom has already had *years *of experience in solving problems and mental math involving fractions, decimals, and percentages. *Honest!*

**Think back over the past 24 hours. How often did you use fractions? Think about a percentage? Interact with a decimal?***(other than as part of instruction)*

**Ok now, how often did you use or encounter the concept of ½? 10%? .25? ***How about quarters, dimes or dollars?*

Clearly, adults encounter and use these types of ** benchmark numbers** every day in various facets of their lives – in their work, with their families, and out in the community. See if these examples sound familiar:

*“Split that with your sister – each of you can have HALF.”**“I want to see a 100% team effort!”**“Thank you for shopping with us, you saved $3.75.”*

Helping students to realize that they *ALREADY SUCCESSSFULLY USE* fractions , decimals and percentages is one way to combat anxiety and “I can’t” attitudes. Another recommendation is to incorporate activities using these **friendly ‘fractional numbers’ **into instruction with ALL learners – even those still learning their basic math facts.^{1} Note that these recommendations are not limited to adult education – the *Common Core State Standards* *for **Mathematics* call for fractional concepts to be explicitly taught at the 3^{rd} grade level, and introduced less directly even earlier (via telling time, comparing measurements, dividing shapes into parts, etc.). These standards also state:

*“**Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.” (**CCSS-M Introduction**)*

Thus of course, as always, it is important to **keep it REAL.** Instruction should be based in everyday contexts that are meaningful to your specific group of learners. Here are some example contextual activities from the *EFF Preparing for Work Curriculum *that address fractional concepts: *A Typical Day/Time on Task*

It is also important to note that many adult learners working at more advanced levels of math instruction may have an incomplete understanding of fractional concepts. They may have memorized a process, or algorithm, but cannot easily or readily apply it to real-world situations, or easily convert from fractions to decimals to percentages. Again, some work with basic benchmarks can help – even those who think they ‘know’ fractions, etc..

** Could your students easily move from ‘80 out of 100’ to ‘80 percent’ to ‘8 tenths’?***Do they seem to confuse fractions, decimals and percentages or give up when asked?*

In *Algebraic Thinking in Adult Education *(2010), Lynda Ginsburg emphasizes the importance of ** making connections **among

**of the same information – symbols, tables, graphs, etc.**

*multiple representations*^{2}This idea applies to number concepts for fractions, decimals and percents as well. Learners need instruction and practice in understanding the equivalencies between fractions, decimals, and percentages to deepen their conceptual understanding of these numbers. Activities that mix together fractions, decimals and percentages, and/or ask students to move from one representation to its equivalent (10% to 1/10 to .1) are effective tools for both assessing and strengthening understanding.

*Comparing Numbers*is one example of such an activity (also from the

*EFF Preparing for Work Curriculum).*

## Teaching Text Structure and Signal Words: A Key to Reading Informational Text with Understanding

**How much ‘informational text’ do you read in a day?** (as opposed to narrative/fiction reading)? *Consider ALL the reading you do – including all the ‘incidental’ and ‘necessary’ reading (like billboards, headlines, package directions, blogs, e-mail at work, etc.)*

**How much ‘informational text’ do you think your students read?** *How much do they NEED to do in order to reach their learning and career goals?*

Informational (or * expository*) text is the text we use to

*learn about something*. For most of us, informational text forms the majority of the necessary reading and writing we do in a day. As adults at home, at work, or in our communities, we are constantly faced with informational text that we need to read with understanding.

In recognition of this, the EFF Performance Continuum and the Curriculum Framework for the Read With Understanding standard emphasizes the importance of students reading a wide variety of different kinds of materials for varying purposes, particularly in real-world contexts. This aligns with the Common Core State Standards Initiative’s College and Career Readiness Anchor Standards for Reading which states: *Reading is critical to building knowledge in history/social studies as well as in science and technical subjects. …Students must be able to read complex informational texts in these fields with independence and confidence because the vast majority of reading in college and workforce training programs will be sophisticated nonfiction.*

**Yet research shows that informational text presents greater burdens to reading comprehension** over narrative text. This can present a problem since so much of what we need and want to read as adults is, in fact, expository in nature.

**What strategies do YOU use to read informational text****? ***To make it easier to analyze and comprehend?*

At home, at work, or in our communities, adults are constantly faced with informational text that we need to read with understanding. We all use a variety of strategies when trying to comprehend text. One strategy that might be especially helpful to us, and a strategy that we can teach to adult learners, is recognizing text structure.

We all use a variety of strategies when trying to comprehend text. One strategy that might be especially helpful to us, and a strategy that we can teach to adult learners, is **recognizing ****text structure****.** Every informational text has a structure. Depending on what the writer of the text wants to accomplish with it – the writer’s purpose – the information in the text will be organized into one of several possible structures.

So for instance:

If writers want to focus on… |
the text structure might be: |

Steps in a process or a logical chain of events ………………… | Sequence |

Similarities or differences between two ideas …………………. | Comparison / Contrast |

The impact of an event or the reasons that something happened | Cause / Effect |

Details to elaborate on a topic ………………………………….. | Description |

A way to resolve a situation, or a suggested course of action … | Problem solution |

Skilled readers are able to identify the structure of the texts they are reading – even if they are not aware that they are doing it (since the more skilled a reader is, the more “automatic” this kind of behavior becomes). This ability helps to clue them in on the *purpose of the text* and to understand what they are reading more deeply.** Teachers can explicitly teach students how to recognize and use text structure** (as part of the process of reading that is described by the EFF standard *Read with Understanding)*.

**What approaches or strategies might you – as an adult reader – use to recognize different informational text structures?** *What strategies do you teach your students to use?*

An important strategy that writers employ to help readers understand their main points is the use of “**Signal Words**”. Signal words are the words in a text that suggest its structure. Skilled readers use these signal words to identify and follow the text structure that the writer of the text intended. Let’s consider the most common kinds of text structure and some of the signal words used for each. *[Click on the image below to view the full-sized pdf document.]*

**But WAIT, here’s an important note to remember** (making things just a bit more complicated): While one particular text structure will probably predominate in any given text, other structures may also be present in that text. In other words, **texts may include more than one text structure. **You will need to assist students to determine the **primary text structure** for a document. **If readers are aware of text structures, they can select strategies for reading comprehension that are likely to be effective.**

Many readers need * direct instruction* to develop awareness of basic text structures. Teachers should provide

*explicit*and

*systematic*instruction in text structure, supported by

**. Here are some practices that can be especially effective:**

**Please share with us your thoughts on strategies for supporting adult learners in reading Informational Text** – its importance both in and outside the classroom, how you address it, any ‘ah-has’ you’ve had, etc. **Below are some questions to get you started**:

*What kinds of informational texts do you use in the classroom?*How do you find and select informational texts to use with your adult learners?*What kinds of strategies do you teach your students to use when reading informational text with understanding?*How do you teach these strategies (what examples or approaches do you use)?

**We look forward to reading your thoughts and experiences.**
