OBJECTIVE: Identify [congruent ]and [similar] figures(5-6,
Pp197ff)[1.3.5] ACTIVITIES: Do pages 199-200, Problems 6-20
NOTES: Need to reinformce the meaning of 'same shape' to
include proportional sides. HOMEWORK: Make a mini-poster which
demonstrates 'corresponding sides'.

OBJECTIVE: Divisibility practice; Find the prime factorization
of a composite number(6-2, Pp215ff)[1.1.3] ACTIVITIES: 1)Using
the procedure listed on p213 in Example #1, DETERMINE WHETHER
720 IS DIVISIBLE BY 2, 3, 4,5, 6, 8, 9 OR 10. Review the terms
and practices of prime factorization including [FACTOR TREES.]
NOTES: [[See also Sieve of Eratosthenes]] HOMEWORK: Define in
COMPLETE SENTENCES prime; composite; prime factorization;
factor tree; and the Fundamental Theorem of Arithmetic.
