Capture the rich content in the hundreds chart with Claim Stakers! Players develop knowledge of multiples, divisors/factors, squares, primes, composites, plus even and odd as they study the anatomy of the first 100 numbers. The winner is the first to claim three rows or columns. Strengthens mental computation of one- and two-step problems using the four basic operations. Options invite offensive and defensive strategies. Activity masters include prime number identification and patterns created by multiples, leading to least common multiple and lowest common denominators.

6.NS.2 Fluently divide multi-digit numbers using the standard algorithm.
6.NS.4 Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
6.NS.6.a Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.
6.NS.6b Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
6.NS.7 Understand ordering and absolute value of rational numbers.
7.NS.2 Apply properties of operations as strategies to add and subtract rational numbers.
7.NS.2 Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
