Additional Practice Questions
Create a pattern with shapes that repeats every 4 steps and describe it.
easyAnswer: A simple pattern could be a triangle, circle, square, star, and then repeat. This teaches recognition of cyclic patterns.
Why are all numbers in the times-2 table even? Discuss the properties of multiplication.
mediumAnswer: Multiplication of any number by 2 results in an even number because 2 is itself even, thus any multiple remains divisible by 2.
Find out the next five numbers in the sequence 2, 4, 6, 8, __.
easyAnswer: The next numbers are 10, 12, 14, 16, 18. The pattern increases by 2 each step.
Create your own sequence that alternates between increasing by 3 and decreasing by 1 starting from any number.
mediumAnswer: Starting with 5: 5, 8, 7, 10, 9, 12, 11... The pattern follows increase by 3, then decrease by 1.
How do pairing objects and forming groups assist in learning division?
mediumAnswer: Pairing objects in groups helps visualize division as it shows how a set can be divided into equal parts, aiding in understanding quotient and remainder.
Design a floor pattern using tiles of two colors such that no two tiles of the same color are adjacent.
hardAnswer: A checkerboard pattern with colors alternating, for example black and white, ensures that no two tiles of the same color touch.
