Bridge designs

The flat bridge held 8 coins, the arch held 16 coins, the folded bridge held 24 coins, and the tube held 20 coins. Use the bar tools to compare the results.

1. Which table correctly records the results?AFlat 16, Arch 8, Folded 24, Tube 20 coinsBFlat 8, Arch 16, Folded 24, Tube 20 coinsCFlat 8, Arch 16, Folded 24, Tube 20 cmDFlat 8, Arch 16, Folded 20, Tube 24 coins

2. How many more coins did the folded bridge hold than the flat bridge?A32 coinsB24 coinsC8 coinsD16 coins

Seedling height

The same seedling was measured on four days. Use the line tools to show height over time. Join neighboring points in time order.

Day	Height (cm)
0	3
1	9
2	9
3	15

3. Between which two recorded days was the height unchanged?ADay 1 to day 2BDay 0 to day 1CDay 2 to day 3DDay 0 to day 3

4. What was the total increase in height from day 0 to day 3?A15 cmB18 cmC12 cmD6 cm

Leaf measurements

Each row gives two measurements of the same leaf. Use the scatter tools to compare length and width. Keep the dots separate.

Length (cm)	Width (cm)
2	2
4	4
6	3
8	5

5. Which statement best describes these data?AEvery longer leaf is wider than the previous leaf.BLonger leaves tend to be narrower.CAll four leaves have the same width.DLonger leaves tend to be wider, but there is an exception.

6. How wide is the leaf that is 6 cm long?A6 cmB3 cmC4 cmD5 cm

A rock collection

There are 50 rocks. Use the 50-space circle to show the parts. Place categories in table order, starting at the top and moving clockwise. Count spaces between marks.

Rock type	Count
Basalt	15
Granite	10
Sandstone	20
Marble	5

7. What percentage of the collection is sandstone?A20%B30%C40%D50%

8. How many of the circle’s 50 spaces should the basalt slice occupy?A15 spacesB30 spacesC10 spacesD35 spaces

Check the scales

Use the bridge results: Flat 8, Arch 16, Folded 24, Tube 20 coins. The bar grid has 16 rows. Then examine the equally spaced ticks below for Question 10.

9. Your bridge bar graph starts at zero and has 16 rows. Which equal scale fits all four bridge results?A1 coin per small squareB2 coins per small squareC0.5 coins per small squareD0.25 coins per small square

10. A student labels four equally spaced ticks 0, 4, 8, 16. Which replacement makes every numerical jump equal?A0, 4, 12, 16B0, 8, 12, 16C0, 4, 8, 16D0, 4, 8, 12

What does the evidence say?

Use this graph of books read by four groups to evaluate both claims.

Group	Books read
Cedar	12
Oak	24
Pine	18
Maple	6

11. A student claims, “Oak read twice as many books as Cedar.” Which response is supported by the graph?ASupported: Oak read 24 books and Cedar read 12.BContradicted: Oak read only 12 more books than Cedar.CCannot tell: the graph does not show reading time.DSupported: Oak’s books must have been twice as long.

12. A student claims, “Oak spent the most time reading.” Which response best evaluates that claim?ASupported: Oak read the most books.BContradicted: Maple read the fewest books.CCannot tell: the graph shows books read, not time spent reading.DSupported: every book takes the same amount of time to read.
