1 #3558 ACE MATH FOR KIDS: VOLUME II, PART 3 Grade Levels: minutes VIDEO RESOURCES SOFTWARE 1996 DESCRIPTION Addy, the animated character, uses many examples to teach multiplying with 2-digit factors, finding 2- digit quotients, and metric measurement. Presents the meter, liter, and gram vocabulary of the metric system. Encourages viewer interaction in each of the three segments and pauses for practice. ACADEMIC STANDARDS Subject Area: Mathematics Standard: Understands and applies basic and advanced properties of the concepts of measurement Benchmark: Knows approximate size of basic standard units (e.g., centimeters, feet, and grams) and relationships between them (e.g., between inches and feet) (See Instructional Goal #4) Benchmark: Understands the basic measures of perimeter, area, volume, capacity, mass, angle, and circumference (See Instructional Goal #4) Standard: Uses basic and advanced procedures while performing the processes of computation Benchmark: Adds, subtracts, multiplies, and divides whole numbers and decimals (See Instructional Goals #1, #2, #3) Benchmark: Understands the properties of and the relationships among addition, subtraction, multiplication, and division (e.g., reversing the order of two addends does not change the sum; division is the inverse of multiplication) (See Instructional Goals #1, #2, #3) Benchmark: Knows the language of basic operations (e.g., "factors," "products," "multiplication") (See Instructional Goals #1, #2, #3) 1 Funding for the is provided by the U. S. Department of Education
