2. Soap Supply:Lewis & Clark knew they were very dirty after a long day of exploring. They did not want to smell bad in the presence of a lady (Sacajawea). Clark knew he sweated more than Lewis, so he took 7 bars of soap from the 12 bars they had stocked up. How many bars did this leave for Lewis? Hint: Cover up 7 bars, count the bars of soap left.
3. Soap Supply Answer: 12 (original # of bars of soap) – 7 (taken by Clark) = 5 (# of bars left for Lewis)
4. Apple Askings: Sacajawea had one apple in a basket. Lewis and Clark gave her three apples each. How many apples does Sacajawea have now? Hint: Sacajawea = 1 apple; Lewis = 3 apples; Clark = 3 apples
5. Apples Answer: 1 apple (Sacajawea) + 3 apples (Lewis) + 3 apples (Clark) = 3 apples total
6. Egg Excitement: Lewis & Clark encountered a hen on one of their stays. She laid three eggs three days in a row. How many eggs did she lay in all? Hint: 3 eggs are laid per day. There are 3 days total.
7. Egg Excitement Answer: 3 eggs x 3 days = 9. This can also be solved by adding 3, 3 different times, or (3 + 3 + 3) since there are 3 eggs a day and 3 days total.
8. Dime Divvying:“Washing Tea” is laundry soap. Lewis had 50 cents. How many boxes of “Washing Tea” could Lewis buy if they cost 10 cents each? Hint: How many dimes make 50 cents?
9. Dime Divvying Answer: 10 goes into 50 five times. 50/10 = 5. This means that Lewis could buy 5 boxes of “Washing Tea”. Also know that a dime is 10 cents. 50 cents is equal to 5 dimes.
