Ten pictured objects, each already marked SANK or FLOATED, feed a picture graph on this 3-page kindergarten sheet. Students color one box per object in a Sank column or a Floated column, with room for 8 boxes in each. Page 2 asks how many sank, how many floated and which group has more. It matches Common Core K.MD.3 and K.CC.6, and the answer key gives the totals of 4 and 6 and the names in each column.
K.MD.3
“Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.”
Students place ten objects into the Sank and Floated columns and count each one.
K.CC.6
“Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.”
Question 3 asks which group has more, comparing four boxes with six.
Ten cards, each with an object and a label. The rock, key, coin and marble sank. The cork, leaf, duck, sponge, ball and bottle cap floated.
A grid with two columns, Sank and Floated, eight boxes high and numbered 1 to 8. Students color one box for each object.
Two answer boxes for how many sank and how many floated, then a Sank or Floated checkbox for which group has more.
Four boxes colored in Sank, six in Floated, with the object names listed, and the answers 4, 6 and Floated.
Color together
Do the first two objects on a projected copy so students see that each card gets one box and no more.
Count in pairs
Partners point to each colored box and count aloud before writing the numbers on page 2. Four and six are small enough to count by pointing.
Your own results
Run the same test with real objects, then have students rebuild the graph from your class results and compare it to this one.
