Arrays and Money

1. Is the number even or odd? Try to split it into $2$ equal groups.

a) $8$ cookies shared between $2$ friends: each friend gets $\underline{\quad}$ cookies. Even or odd? $\underline{\quad}$

b) $13$ grapes shared between $2$ plates: can you split them evenly? $\underline{\quad}$. Even or odd? $\underline{\quad}$

c) Write the next three even numbers after $10$: $10, \underline{\quad}, \underline{\quad}, \underline{\quad}$

d) Write the next three odd numbers after $11$: $11, \underline{\quad}, \underline{\quad}, \underline{\quad}$

2. Look at this array of stars:

$\text{⭐ ⭐ ⭐ ⭐ ⭐}$ $\text{⭐ ⭐ ⭐ ⭐ ⭐}$ $\text{⭐ ⭐ ⭐ ⭐ ⭐}$

a) How many rows? $\underline{\quad}$

b) How many columns? $\underline{\quad}$

c) Write an addition equation for this array: $\underline{\quad} + \underline{\quad} + \underline{\quad} = \underline{\quad}$

d) Total number of stars: $\underline{\quad}$

3. Draw (or describe) an array with $4$ rows and $3$ columns using dots.

a) How many dots in each row? $\underline{\quad}$

b) Write an addition equation: $\underline{\quad} + \underline{\quad} + \underline{\quad} + \underline{\quad} = \underline{\quad}$

c) Is the total ($12$) even or odd? $\underline{\quad}$

4. Count the money.

a) You have $3$ dimes. Each dime is worth $10$ cents.

$10 + 10 + 10 = \underline{\quad} \text{ cents}$

b) You have $1$ quarter and $2$ nickels. A quarter is $25$ cents and each nickel is $5$ cents.

$25 + 5 + 5 = \underline{\quad} \text{ cents}$

c) You have $1$ dollar bill and $3$ dimes. How much money do you have in total?

$\$1.00 + 30 \text{ cents} = \$\underline{\quad}$

5. A toy costs \0.75$ (75 cents). You have these coins:

• $2$ quarters ($25$ cents each)
• $3$ dimes ($10$ cents each)
• $1$ nickel ($5$ cents)

a) How much money do you have in all?

$25 + 25 + 10 + 10 + 10 + 5 = \underline{\quad} \text{ cents}$

b) Can you buy the toy? $\underline{\quad}$

c) If you buy the toy, how much change do you get back?

$\underline{\quad} - 75 = \underline{\quad} \text{ cents}$
