Maya Math Game

PRACTICE ROUND 4

Addition

Let’s add! Now that you practiced the Maya base-20 system and symbols, it is time to start doing some real math. In this practice round we are going to look at addition and will use a method called reduction to get the final answer. DIRECTIONS Drag the correct symbol(s) from the gold boxes into the white boxes to match the number. Then complete the reduction for the final answer. Drag new symbol to replace a value, or click symbol to remove.

HINT: When adding or subtracting you may need to use the process of reduction to get to the final answer. CLICK HERE for a quick reduction lesson.

CLUE #3: Today, my son came to work with me, but he was so distracting. I was trying to count while he wanted to play hide-and-seek among the rows.
CLUE #4: My occupation requires me to build a troje or storage bin in English. The troje cannot be too big or too small. I use Maya math to help me determine the size of the bin based on the size of my workspace.
CLUE #5: My wife just told me her shopping list and now I must calculate how much I need to sell in order to get everything she asked. Hopefully, I will have some left over to bring back chocolate to my family.
