## 4th Grade Math Enrichment Overview

Long division? Piece of cake! Put away your calculator and become a number crunching wizard.

This program is designed to make you “the” expert number manipulator. You’ll understand why you carry when you multiply. You’ll learn how multiplication and division “work”.

*Suppose you want to buy 12 candy bars, which cost $1.39 each for your friends. You hunt under your bed and find 48 quarters, 42 dimes, and 10 nickels. Do you have enough money?* Easy. You’ll add, subtract and multiply decimals like a pro. And, you’ll apply what you’ve learned to practical problems.

Enjoy competition? Test your number crunching power in a contest. Win a prize.

Numbers can also be magical. Explore relationships between numbers and play with elementary algebra. Turn numbers into symbols — and back again. And apply “logic” to solve number problems.

*Suppose Ms. Jones has 216 books on the shelf and 8 students in her class. Can she give each student the same number of books? If another student joins the class, can the books be equally divided? Or not.* Take shortcuts with divisibility “rules” — and apply these “rules” to real life situations. Finally, wrestle with basic geometric principles..by building triangles with sticks to learn one of the rules of triangles. Then measure all sorts of angles.

Strong computation skills are the foundation of mathematical success. We’ll make sure that you’re rock solid.

**Who**: Recommended for incoming 4th grade students who are seeking additional challenge

### The SelectiveMath 4th Grade Math Enrichment Program

- Is offered in a 5-day session (one week long), Monday through Friday and is 3 hours per session or 15 hours total.
- Limits class size to 20 students
- Includes hands-on workshops and exercises where students get additional practice — and have fun.

**Cost**: $350 for a week long session

**Schedule**: We will start registration for our Summer 2018 4th Grade Math Enrichment Program in **April 2018 **and classes will run in** August 2018**. In the meantime, please *contact us* if you have any questions.

### Program Format

Each session is divided into three parts:

**Concept Review**. Students will interactively work through problems in each topic area to ensure that the concepts are well understood.

**Application**. Students will apply concepts in real life simulations or word problems to gain practical experience.

**Game/Contest**. Students work through challenge questions and compete for prizes, either in teams or individually.

### 4th Grade Math Enrichment Program Syllabus

**Session 1: Introduction to Multi-Digit Multiplication & Long Division**

- One-by-one multiplication (e.g., 8 x 7)
- Two-by one multiplication (e.g., 21 x 4)
- Two-by-two multiplication (e.g., 32 x 21)
- Basic long division (e.g., 318/6)
- Symbols (e.g., evaluate equations with symbols)

**Application**: Multiplication & division word problems

**Game/Exercise**: Jeopardy (multi-digit multiplication & symbols)

### Session 2: Decimal Addition & Subtraction

- Adding decimal numbers (e.g., 5.102 + .898)
- Subtracting decimal numbers (e.g., 1.04 -.32)
- Two-digit division (e.g., 2,142/51)

**Application**: Money word problems

**Game/Exercise**: Jeopardy (long division & decimals)

### Session 3: Decimal Multiplication & Division, Venn Diagrams & Logic

- Multiplying with decimals (e.g., .142 x .61)
- Dividing with decimals (e.g., .216/.003)
- Logic: Venn diagrams (e.g., two and three statement Venn diagram problems)

**Application**: Decimal multiplication & division word problems

**Game/Exercise**: Jeopardy (decimal multiplication & division)

### Session 4: Angles & Triangles

- Angles (e.g., working with acute, right, obtuse, complementary & supplementary angles)
- Logic (e.g., common factors using Venn diagrams, addition equations with symbols)

**Application**: Assemble triangles with sticks, categorize as equilateral, isosceles or scalene)

**Game/Exercise**: Jeopardy (angles & triangles)

### Session 5: Factoring, Prime Numbers & Divisibility

- Prime numbers (e.g., list the first 10 prime numbers)
- Factoring (e.g., which number has more prime factors — 24 or 30)
- Logic (e.g., subtraction equations with symbols)
- Divisibility (e.g., how do you know if a number is divisible by 3, or by 9?)

**Application**: Divisibility word problems

**Game/Exercise**: Jeopardy (prime numbers & divisibility)
