Match the words in column A to the words in column B to form compound nouns, as in the example. The first compound noun is toothbrush.

Okay, class! Let's complete the compound nouns exercise. Remember, a compound noun is formed when two or more words are joined together to create a new noun. Here's the completed list: 1. toothbrush 2. notebook 3. camp knife 4. pen chair 5. key board 6. arm site Explanation: * **toothbrush** is already provided as an example, so we know that we need to combine the words from column A and B to make new words. * **notebook** is formed by combining 'note' and 'book'. * **camp knife** we combined 'camp' and 'knife'. * **pen chair** combines 'pen' and 'chair'. * **key board** combines 'key' and 'board'. * **arm site** combines 'arm' and 'site' Remember, sometimes you might need to think creatively to figure out the correct compound noun. Good job everyone!
