Math 100L Lesson 5 PDF

Have a copy of your Textbook Reading available for your appointment.

Read the following information to your Speaking Partner.

In English, the words “OK,” “so,” and “now” are used constantly when speaking. They are informal transition words—words that help tie the speech together as you move from one point to another. We are just focusing today on these three transitions, but there are many more informal and formal transitions.

Transition words are used to move from:

  • one main point to the next

  • the main point to supporting points

  • one supporting point to another supporting point

In this week’s video lecture, notice how Brother Baird uses transitions to connect his ideas:

  • “OK, so 6 plus 8 plus 6 plus 8.”

  • “So the perimeter was 3 meters plus 15 meters plus 3 meters plus 15 meters.”

  • “Now dealing with variables, and you’re going to be dealing with a lot of variables for the remainder of the course.”

  • “So let’s do something that you guys have done before.”

Transition Word and Meaning:

  • OK = Used to signal that everybody understands

  • So = Used to signal the result, the consequence

  • Now = Used to signal the present moment

Discussion Questions

  1. Have you noticed the use of these words in Brother Baird’s lectures?
  2. Do you use transitions to guide your listeners through your speech?
  3. Try using the words above to discuss your experience keeping track of your expenses.
    • Do you find it easy or difficult to keep track of your money?
    • What system do you have for writing down your purchases?
    • Do you keep your receipts when making purchases?
  4. 4. Ask your speaking partner to share an experience with budgeting and see if you can hear the transition words above.

Pronunciation Practice

Practice saying your geometric shapes in English. After you say the word, draw a picture for your Speaking Partner. The shapes are in your math textbook.

  • rectangle
  • parallelogram
  • trapezoid
  • triangle
  • rectangular solid
  • circle
  • cylinder
  • cone
  • sphere

Practice saying the following numbers and expressions:

  • 4πr²
  • 6 78 - 13 38
  • 2(32) + 5(4) + 8m
  • 2(n + 9)
  • .045
  • –102
  • $37.89
  • 4,706.25
  • –6 ½
  • .345

The -ed ending in past tense verbs

The simple past of a regular verb ends in -ed. The pronunciation of this final sound depends on the sound at the end of the base verb. There are three possible sounds.

If the verb ends in ...pronounce the simple past by adding ...Examples

a voiced sound

a “d” sound.

study

studied

learn

learned

an unvoiced sound

a “t” sound.

work

worked

help

helped

a “t” or “d” sound

a schwa sound plus “d” (“ud” or “ed”).

visit

visited

end

ended


Listen to your speaking partner say the following sentences from the video lecture:

  • How far is it if I started right here? (Which ending sound do you hear?)
  • If you’ve taken any health science courses you may have studied a pericardium. (Which ending sound do you hear?)

Now you practice saying the following sentences. First read the sentence; then say the sentence without looking at it.

  • Joseph moved into his new place.
  • I helped clean the Institute building last week.
  • I watched the video lecture for math last night.
  • She lifted the box and placed it on the table.
  • The children waded through the stream.
  • Maria opened the present she received for her birthday.

Take turns making up sentences with your speaking partner using the simple past forms of the following verbs.

    • change
    • complete
    • add
    • subtract
    • multiply
    • divide
    • require
    • walk
    • stop
    • wait
    • want
    • prefer
