Pearl Diver HD vs Tri This Math

Throw on your diving helmet, and head into the depths of the sea! Master the number line, including fractions and decimals, while gathering beautiful pearls. Will you find the elusive black pearl? • Ideal for elementary and middle school students, grades 3-8. Developed by mathematics educators, researchers, and game developers at the Learning Games Lab at New Mexico State University. Games developed by the Learning Games Lab undergo a rigorous instructional design process, extensive user testing, and input from learners, teachers, and researchers. Pearl Diver addresses Common Core standards relevant to the number line and properties of numbers, including: • Understanding numbers, ways of representing numbers, and number systems. • Understanding and representing commonly used fractions. • Understanding fractions as part of unit wholes and as locations on number lines. • Comparing and ordering fractions, and finding their approximate locations on the number line.

Need to practice the four basic arithmetic operations? Need to practice creating number sentences with three numerals? Need to practice using 3 addends for sums to 20? Need to practice mixed operation number sentences with totals to 99? In each turn players are given four numerals. Each player has five turns. Use three of the four numerals and the basic arithmetic operations (+, -, x, ÷) to form an equation that equals any empty square (or one occupied by your opponent) on the game grid. The total for each number sentence is computed using standard order of operations.... multiply and divide (left to right) then add and subtract (left to right). Drag that total to the corresponding grid square. Your accumulated point total for each match is updated after each term and is the total of all the grid squares you occupy plus any BONUS points earned. You may not use an answer grid square you occupy, but you can ‘steal’ your opponent’s square. In that case, your score increases and your opponent’s score decreases by the same amount. Grid size options include 20, 25, or 50 squares. The numeric range for the grids includes 14 options: 1-20; 11-30; 1-25; 15-29; 1-50; 50-99 and others. Some Common Core connections: Add and subtract within 20. CCSS.MATH.CONTENT.1.OA.C.5 CCSS.MATH.CONTENT.2.OA.B.2 Multiply and divide within 100.
