It’s nice to hang out on a couch with a pet. But sometimes those fuzzy animals can act like, well, animals. If a cat gets bossy, you might end up smooshed into one corner with a paw or tail in your face. So why not give cats their own couch? Lately people have been crocheting cat couches, like you see in the picture! Crocheting is a way of looping yarn into little knots, or stitches, to make fabric. It took this crocheter about 6 hours and 350 yards of yarn to make a couch, but now that kitty is sitting pretty!
Wee ones: If a person’s couch has 3 cushions and a cat’s couch has 2 cushions, which couch has more cushions?
Little kids: Animals put their feet on the couch, but we don’t! If 2 cats are sitting on a couch with you, how many paws are on the couch cushions? Bonus: If it takes 6 hours to make a kitty couch, and twice as long to make a couch for a big dog, how long does the big dog couch take?
Big kids: Different sizes of yarn will make different-sized stitches. Thick yarn might only need 6 stitches to make 2 inches of fabric. How many stitches of that yarn would it take to make 1 foot, or 12 inches, of fabric? Bonus: 350 yards is a lot of yarn! If the playground at the park is on a rectangle 70 yards long and 40 yards wide, can that kitty couch yarn wrap all the way around the yard?
The sky’s the limit: Using the numbers in Big kids question, how many stitches are in those 350 yards of yarn?
Wee ones: The person’s couch, because 3 is more than 2.
Little kids: 8 paws, because 4 + 4 = 8. Bonus: 12 hours, because 6 + 6 = 12, or 6 x 2 = 12.
Big kids: 36 stitches. If 6 stitches = 2 inches, then there are 3 stitches in 1 inch. 3 x 12 = 36. Alternatively, because 2 goes into 12 6 times, you need 6 sets of 6 stitches, and 6 x 6 = 36. Bonus: Yes! The distance around the 4 sides of the playground is 70 + 40 + 70 + 40 = 220 yards.
The sky’s the limit: 37,800 stitches. Since there are 3 feet in 1 yard, there are 36 x 3 = 108 stitches per yard. We can use partial products to simplify the multiplication from there: 350 x 108 = 350 x 100 + 350 x 8 = 35,000 + 300 x 8 + 50 x 8 = 35,000 + 2,400 + 400 = 37,800.
