Solve each problem. Draw pictures to justify your answers. • Demetri had 14 pennies. Chase gave him some more. Now Demetri has 20 pennies. How many pennies did Chase give him? • Talia and Becca put 17 pennies in a jar. Talia put in 9 pennies. How many pennies did Becca put in the jar? • Lyla has 8 more pennies than Scott. Lyla has 15 pennies. How many pennies does Scott have? (DOK 3)
