Homework: 1. Watch three videos. Decimals Video (adding- Khan Academy) Decimals Video (subtracting- Khan Academy) Decimals Video (comparing- Khan Academy)

2. Write the Farey sequence for F10 and F11. What did you notice about the fractions that were slotted in from F10 to F11? Is there a pattern with the numerators and denominators? Pick 3 consecutive fractions in either the F10 or F11 sequence. What do you notice about the outer fractions (the first and third in the sequence of 3 you picked) and the inner fraction (the second one in the sequence)?
 * Challenge: When you are determining the next Farey sequence (for example, when you went from F3 to F4), what fractions will always be added? Can you write a rule?
