Whole Number<\/strong><\/td>Any number that is not a fraction or decimal. Includes 0 and all positive counting numbers.<\/td>7, 12, and 0 are whole numbers. \u00bd and 3.5 are not.<\/td>Play “Whole Number Bingo”! Write numbers 1-20 on a bingo card. Call out numbers and mark only the whole numbers. Alt text: Whole number bingo card for kids with numbers 1 to 20<\/em><\/td><\/tr>
Width<\/strong><\/td>The measurement of how wide an object is from one side to the other.<\/td>The width of your desk is how far it goes from left to right.<\/td>Measure your bedroom! Use a ruler to find the width of your bed, your desk, and your door.<\/td><\/tr>
Weighted Average<\/strong><\/td>An average where some values are more important (have more “weight”) than others.<\/td>If homework is 30% and tests are 70% of your grade, your final score is a weighted average.<\/td>Calculate your own grade! If you got 80 on homework and 90 on a test, and homework is 40% and tests are 60%, what’s your weighted average?<\/td><\/tr>
Word Problem<\/strong><\/td>A math problem that uses words instead of just numbers and symbols.<\/td>“Lily has 8 stickers. Her friend gives her 5 more. How many stickers does Lily have now?”<\/td>Make up your own word problems! Write 3 word problems about your favorite snacks or toys, then solve them with a family member.<\/td><\/tr>
Wheel Graph<\/strong><\/td>A type of graph with one central point connected to all other points, like a bicycle wheel.<\/td>A ferris wheel is a real-life example of a wheel graph.<\/td>Draw your own wheel graph!

Winding Number<\/strong><\/td>The number of times a closed curve wraps around a fixed point.<\/td>If you walk around a tree 2 times and come back to where you started, your winding number is 2.<\/td>Kids draw their own curves and count how many times they wrap around a point to learn this geometry concept.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

<\/span>Quick Practice Questions<\/span><\/h2>\n\n\n\n
    \n
  1. Give an example of a whole number<\/strong> greater than 10 but less than 20.<\/li>\n\n\n\n
  2. A table is 5 feet wide<\/strong>. What is its width in feet?<\/li>\n\n\n\n
  3. A graph has points connected like a wheel. What is this type of graph called? <\/li>\n\n\n\n
  4. A coin is flipped many times. As the number of flips increases, the average number of heads gets closer to 50%. Which math principle does this illustrate? <\/li>\n\n\n\n
  5. Three tests have scores 70, 80, and 90. If their weights are 1, 2, and 1 respectively, what is the weighted average<\/strong>?<\/li>\n<\/ol>\n\n\n\n

    Answer: <\/strong>Any whole number between 11 and 19, for example 12.; 5 feet; Wheel Graph; Weak Law of Large Numbers; Weighted average = (70\u00d71 + 80\u00d72 + 90\u00d71) \u00f7 (1+2+1) = 80<\/p>\n\n\n\n
