15
How can you remember these conversions? Draw a picture, write a story, poem or song to help you remember. 12 inches = 1 foot 3 feet = 1 yard

Now lets practice converting inches, feet, and yards. You can use a bar model to help you.
17
1 Yard 1 foot 1 yd = 3 ft
18
How Many feet are in 11 yards and 2 feet? We multiply the 11 yards by 3 ft to get the number of feet in 11 yards, and then add on the 2 feet. 11 yd 2 ft = = 11 X 3 ft 2 ft = 33 ft33 ft + 2 ft = 35 ft 35 ft 11 yd 3 ft So we multiply 11 yards by 3 feet in each of those yards

Now you try some! You can use a bar model to help you.
