Ethan wants to buy one teddy bear
for his son and one doll for his daughter. How much do they cost in total?
We can see from the price tag that
the teddy bear costs 24 LE and the doll costs the same amount. To find the total cost, we need to
add these two amounts together. What is 24 plus 24? Let’s add using the number
line. We’re going to start at 24. And if we partition or break 24
apart into its tens and ones, we could start by adding 20 and then add the four. So what’s 24 plus 20? It’s 44. Now, what we need to add is the
four, and four more than 44 is 48. The total cost of the doll and the
teddy bear is 48 LE. We started at 24 on the number line
and counted forward 20 and then four more. The cost of the teddy bear and the
doll is 48 LE.
