Y QUESTIONS!

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.

Soap Supply Answer:12 (original # of bars of soap) – 7 (taken by Clark) = 5 (# of bars left for Lewis)

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

Apples Answer:1 apple (Sacajawea) + 3 apples (Lewis) + 3 apples (Clark) = 3 apples total

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.

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.

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?

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.

Georgia Performance Standards:M1N1. Students will estimate, model,

compare, order, and represent whole numbers up to 100.

M1N3. Students will add and subtract numbers less than 100, as well as understand and use the inverse relationship between addition and subtraction.
