## Homework Hotline

**Who are we?**

The Harvey Mudd College Homework Hotline is a * free*over-the-phone math and science tutoring service for students in

**grades**

**4 through 12**. We’re open five nights per week,

**Monday****. We’ve always been a free service, and we always will be.**

*through Thursday, from 6 p.m. to 9 p.m. PST*Our tutors are all students at Harvey Mudd College, one of the top-ranked STEM (science, technology, engineering, and mathematics) schools in the nation, and they’re all selected for their technical expertise AND their superior communication skills. They get extra training to make sure they give you the best possible service!

**How did we get here?**

We launched in 2010 with the help of the Homework Hotline at Rose-Hulman Institute of Technology. We provide free, over-the-phone tutoring to students in the greater Los Angeles region, Inland Empire and beyond. Since then, we’ve helped thousands of students learn math and science, one call at a time!

**How does it work?**

A Homework Hotline tutor will assist the student caller with guiding questions and encourage the student to be an active participant in their learning. The tutor will use the student’s prior knowledge and encourage the student to use all available resources first. The tutor will also invite the student to write down procedural steps in their own words to help the student solve similar problems on their own.

The goal of the tutor is to help the student caller with one homework question, and then encourage the student to try solving similar problems on their own. The student caller is invited to call the Homework Hotline again if they get stuck on another problem (similar or different to the current question).

Student privacy matters to us. We don’t ask for names or phone numbers, though we do ask callers to share their school and grade level for our reporting purposes. We are funded by the Simons Foundation and Harvey Mudd College.

For a more effective call, please be prepared with the following:

- Homework assignment
- Textbook
- Paper
- Pencil/pen
- Calculator

## Calendar

We are committed to guiding student callers through their math and science homework questions, Sunday through Thursday, from 6 to 9 p.m. There are certain days of the academic year when we will be closed. These include national holidays and Harvey Mudd College semester breaks and finals week.

## Teach Kids Math With Model Method

Ever teach kids math using the Model Method but discovered that you do not know how to draw the diagram? If you have, you might want to know that you are not alone. Many parents are facing the same problem as you simply because you were not taught Math this way when you were young. The Model building approach to solving word problems was developed locally years ago by a team of educators from the Singapore Ministry of Education led by Dr Kho Tek Hong. This team included some well-known educators like Mr Hector Chee, Sin Kwai Meng, among others, all of whom are very experienced Mathematics teachers. They helped to promote the method to Singapore teachers in the mid-eighties, and this method has since been widely used in the teaching of kids math in primary schools (or elementary schools if you prefer) in Singapore. Kids in Singapore are introduced to the method from as young as Primary One (the equivalent of Grade One).

Students in Singapore (and probably everywhere else) typically find word problems difficult due to various reasons: they are weak in the Mathematical language; they have limited understanding of the arithmetic operations; they are unable to relate the knowns to the unknowns when the problem structure is difficult to understand; and they are unable to analyze problem situations.

This method is especially useful when: you teach kids who respond better to visual stimuli (e.g. pictures, drawings, etc); you try to provide math homework help but the conventional methods do not really work well with your kids; and your kids has not learnt algebra yet and solving the math problems with algebra is not an option.

However, without proper guidance, you may not be able to experience the full benefits of the Bar Model Approach. We have therefore created this website to share with you how the Method is applied to different scenarios so that you could confidently teach kids math problems even when you do not have prior knowledge of this Method. It essentially becomes a good entry level tool to help the kids understand and break the questions down into component parts making solving and learning math a breeze.

What is Model Method?

The model approach requires kids to draw rectangular boxes to represent part-whole relationships and math values (both known or unknown values) in the math problems. The word problems are typically designed to depict real-life situations such as grocery shopping and division of money.

By drawing such boxes/blocks, they can visualize the math problems more clearly and are able to make tacit knowledge explicit. Word problem solving is a major part of the curriculum in Primary Mathematics in Singapore.

This technique of model building is a visual way of picturing a situation. Instead of forming simultaneous equations and solving for the variables, model building involves using blocks or boxes to solve the problem. The power of using models can be best illustrated by problems, often involving fractions, ratios or percentages, which appear difficult but if models can be drawn to show the situation, the solution becomes clearer, sometimes even obvious.
