See-Through or Not? Read and Sort

Before each page, let your child try the test with real objects, such as pressing a pillow and a spoon or dropping a cork and a key in a bowl of water. Then read, sort and check with the answer key.

Read about transparent and opaque, then sort plastic wrap and a window pane from a wooden door and pan. Something opaque does not let light pass through. The directions on the page read: Read the passage. Then, turn the page, sort the cards and answer the questions. On page 2: Write each card from the Card Bank on a line in the column where it belongs, lines 1 to 6. Then, write the answers to questions 7 and 8 on the lines. The answer key covers the questions on page 2.

Yes, both. We made it for 2nd Grade material properties, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with sorting by properties. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

These pages sort by hardness (hard or soft), flexibility (bends or snaps), floating or sinking, and whether light passes through (transparent or opaque). A Venn diagram page sorts nine objects as round, smooth or both (2-PS1-1).

Flexible things bend without breaking, like a pipe cleaner, a garden hose or a strip of paper. Brittle things break instead of bending, like a dry spaghetti noodle, a stick of chalk or a cracker.

Transparent means light passes through, so you can see through it, like plastic wrap or a window pane. Opaque means light is blocked, like a wooden door or a metal pan, which makes a shadow.

Yes. All 5 sheets have an answer key, and the sort keys accept the cards in any order within a column.
