    3. Mental Math • Count up and down by 3’s between 3 and 36. • 4 x 75 279 + 350 • 250 - 199 $15 + $7.75 • Double $1.50 800/40 • 4 x 12, ÷ 6, x 8, - 4, ÷ 6, x 3, ÷ 2

    4. When we write a number in expanded notation, We write each nonzero digit times its place Value. Expanded Notation Write 250 in expanded notation: (2 x 100) + (5 x 10)

    5. AM: Runs from midnight to just before noon PM: runs from noon to just before midnight We can use the Later-Earlier Difference Pattern to solve elapsed time problems. Elapsed Time

    6. Jason started the marathon at 7:15 a.m. He Finished at 10:10 a.m. How long did it take Jason to finish the race? Later 10:10 am - earlier - 7:15 am 10:10 - 7:15

    8. A 1 ½ + ¾ = 2 ¼ 20 ¼ - 2 ¼ = 18 inches

    9. A 1 ½ + ¾ = 2 ¼ 20 ¼ - 2 ¼ = 18 inches
