         <description><![CDATA[<div>1) What will Figure 10 look like? Describe or draw it.<br>2) Now move the pattern backwards. What will Figure 1 look like?<br>3) How did you determine what each numbered figure will look like? Is there a pattern that the shapes follow? Is there an equation that can express the figure for any given case?<br>4) Move the pattern back even further. What would figure -1 look like? (That's Figure Negative One, whatever that means!) Describe why your figure makes sense.<br><br></div>]]></description>

         <description><![CDATA[<div>1) How could you find the volume of a complex and irregular shape, like a lemon?<br>2) How could you use a tub of water to find the solution?<br>3) How could you use slices to figure out the solution? <br>4) If you use measurements, how can you account for the curved edges and varying widths?</div>]]></description>

         <description><![CDATA[<div>1) Can you find each number from 1-20 by using an expression with four 4's? For example, ((4+4)/4)+4=6<br>2) Can you find more than one solution for each number?<br>3) Can you find an expression for numbers beyond 20?<br>4) Can you express each number with a similar pattern, such as using three 3's?</div>]]></description>
