These journal prompts focus on
4.OA.4 determine multiples and factors for whole numbers 1-100
and determine whether a given whole number in the range 1-100 is prime or composite
4.OA.5 generate a number or shape pattern that follows a given rule; identify apparent features of the pattern that were not explicit in the rule itself (given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers; explain informally why the numbers will continue to alternate in this way
The 15 journal prompts in this powerpoint are all open ended and encourage students to explain, model, and justify their understanding of prime and composite numbers, multiples and factors, and patterns.
