Counting by Multiplication
Counting by multiplication is a method of counting where you add the same number repeatedly to find the total. This method is more efficient than counting by addition, especially when dealing with larger numbers.
Example:
If you want to count by 3s up to 30, you would start with 3 and then add 3 to get the next number, and so on: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30.
Study Guide:
- Understand Multiplication: Before counting by multiplication, it's important to have a good understanding of multiplication. Make sure you are comfortable with the concept of multiplying a number by another number.
- Identify the Counting Interval: Determine the number you want to count by. This will be the interval at which you add the number to get the next count.
- Start Counting: Begin with the first multiple of the counting interval and continue adding the interval to find the next counts.
- Write Down the Counts: As you find each count, write it down to keep track of the sequence of numbers.
- Check Your Work: Once you have reached the desired total, double-check your work to ensure that you haven't missed any counts.
Practice Problems:
1. Count by 5s up to 50.
2. Count by 4s up to 40.
3. Count by 7s up to 70.
Now you can start practicing counting by multiplication and become more comfortable with this method of counting!

Geometry (NCTM)
Use visualization, spatial reasoning, and geometric modeling to solve problems.
Use geometric models to represent and explain numerical and algebraic relationships.
Measurement (NCTM)
Apply appropriate techniques, tools, and formulas to determine measurements.
Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.
Develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes.
Connections to the Grade 6 Focal Points (NCTM)
Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
