- 1. Using Math in the EFL Classroom for Language Acquisition William M. Balsamo Himeji Dokkyo University Himeji, Japan Email: yamataro670@yahoo. com
- 2. Why use Math in a language class? “ ‘‘ Students are familiar with simple Math, so they are dealing with a known quantity. 1* We use math every day. We may not go on a vacation every day and we may no go to work every day, but there is not one day which passes that we don't use Math is some form or other. 4"‘ Math is task-related. To use math you must think. You must calculate. It's a built in activity so necessary for student involvement.
- 3. Currency Conversions This is a good exercise to have students convert one currency into another. Then use the language: e. g. dollars is worth about in yen. Also useful is using comparatives and superlatives Task: Give the students a list of items with prices in dollars. Tell them they have only 50,000 yen. Have them calculate to see how much they can buy. * Here are some good websites for currency conversions. ‘* http: //www. xe. com/ ucc/ * http: //finance. yahoo. com/ currency

Upper Upper * Math Signs. ,, ,,, ,,, e ﬂight Plus = + Minus = - Multiplication = X Center Left Center Center Have students place the correct sign into the proper box. Lower Left Lower Lower e. g. Teacher: “Place a minus sign Middle Right into the Center Right square. ”
- 6. Changing Sentences into l/ lath Formulas -"'* 1. Teacher says: Ten minus six times two equals ? ?? Students write: 10 - 6 X 2 = 8 2. Teacher says: Nine from twelve plus seven equals? ?? Students write: 12 - 9 + 7 = 10 3. Teacher says: Three multiplied by five less two equals? Student writes: 3 x 5 - 2 = 13 This is an exercise which involves both a mental task and careful listening. Students must also realize that division can be expressed as “divided by” or “into”. Subtraction can be expressed as “minus” or “from". Addition can be expressed as “plus” or “and. ” Multiplication can be expressed by “times” or “ multiplied by. ”
- 7. Reading Large Numbers Students often have difficulty reading large number in English. This is partly because when they write numbers they do not use commas after each third digit. However, I always tell them if they can read three digits. then they can read twelve! Just mark off every third digit from right to left with a comma and remember the words thousand, million, billion, trillion. (no real need to go beyondtrillion) Therefore:

- 9. Class Activity; Using a measuring tape or ruler — part 1 Activity: (Part 1) Divide the class into pairs and give each pair a measuring tape in both inches and centimeters. (The tape should be at least two meters in length. ) Prepare for them a task worksheet with about ten things for them to measure in the classroom. For example; 4. Measure the distance from the door to the window. 5. Measure the width of the door. 6. Measure the height of the desk.
- 10. Class Activity; Using a measuring tape or ruler — part 2 "* Teaching Comparatives and Superlatives After students have measured the items on the activity worksheets give then a second worksheet with sentences which involve the comparative and superlative grammatical form. For example: (use the adjectives “wide”, “high”) 1: The window is than the door by centimeters. 2. The desk is than the chair by centimeters.
- 11. Activity: The Price is Right! ! A simple task which enables students to guess, calculate, convert currency Above are four items found in a duty free shop. Guess the price of each item in dollars. ($1 = 120 yen) Add up the total of the four items. What is your total? Compare with a partner.
