determine factor pairs of whole numbers in the range 1-100
recognize that a whole number is a multiple of each of its factors.
• determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number.
• determine if a number in the range 1-100 is prime or composite.
use manipulatives or drawings of rectangular arrays and/or array models to solve and explain multi-digit multiplication
• apply an understanding of rectangular arrays and area models to connect to the partial products strategy.
recognize that the moon does not produce its own light; it reflects light from the sun.
recognize that the moon revolves around (orbits) Earth in about 28 days as Earth revolves around (orbits) the sun.
describe the changes (patterns) that occur to the observable shape of the moon over the course of about a month that have been recorded in a science notebook.
predict the changes in the observable shape of the moon starting at any point in the cycle.
sequence moon patterns.
compare observable shapes of the moon
explain that the moon’s physical shape does not actually change
explain that Earth’s rotation on its axis causes the moon to appear as though it is moves across the sky in the day or night sky.
