Steve & Blue teach the viewers about counting and doing the math.
Steve and Blue are counting along. Steve needed a new crayon, because he can't write very well due to the fact that it's downright puny. He plans to get a new crayon later. Blue wanted to buy something too. Blue has Steve play Blue's Clues to figure out what she wants to buy. Steve gets his notebook from Sidetable. Now, Steve counts out how many clues he had to find which was 3. He takes 10 steps into the kitchen, near an ice cube tray with 10 ice cubes and an ice bucket with 5 ice cubes (1 was behind the other 4, which were stacked in a 2 x 2 square). He counts out 10 ice cubes in the ice cube tray. After counting the ice cubes, the stacked ones in the bucket co lapses to reveal a paw-print on the other ice cube. Steve draws the 1st clue with a nubby crayon. Steve promises that he'll get a new crayon soon. But first, he helps Mr. Salt and Mrs. Pepper count their apples. Mr. Salt had 3 green one and Mrs. Pepper had 5 red ones. He also had to find out who had more apples. Mrs. Pepper had more apples because 5 > 3. Next, Steve made sure that both Mr. Salt and Mrs. Pepper had the same number of apples; 4. Then, he had to figure out how many they had altogether to take to the picnic. Mr. Salt and Mrs. Pepper had 8 apples altogether because 4 + 4 = 8. After that, he counts how many steps it takes to get from the kitchen to the garden. Then, helps Shovel and Pail count their graham crackers. Shovel had 8 and Pail had 7. Now, Steve had to figure out who had more graham crackers. Shovel had more graham crackers because 8 > 7. Then, Steve had to figure out how many they had altogether to take to the picnic. Shovel and Pail had 15 crackers altogether because 7 + 8 = 15. Steve heads back into the kitchen to the area near the sink. On the left side is 1 picnic basket with a picnic blanket and 1 baguette inside it, while on the right side there are 5 cups (1 has a paw-print on it while the others are stacked), 4 stacked plates, and 10 spoons in 2 rows. He asks how many picnic baskets there are, the viewers answer 1. He then ask how many paw prints there are, the viewers also answer 1. When Steve says they are right, the viewers say it's a clue. Steve agrees (1 paw print, 1 clue), before realizing that the viewers found the 2nd clue. He asked where it is. They said it was on the cup. Steve finds it and concludes that their 2nd clue is a cup. He gets his notebook out and draws the 2nd clue with the nubby crayon. In the Mail time segment, Mailbox counts from 25 to 27. After saying hi to Mailbox, Steve asked 27 of what. Mailbox said there there was 27 stamps in his stamp collecting book and shows them to Steve before giving him his letter. In the letter, a group of 4 kids each wanted the same amount of pizza. They each got 1/4 of the pizza. After that, Steve skidoos into the present store. Steve pulls out his wallet and he had 7 Blue dollars. He buys a new crayon which was worth 2 Blue dollars. He had 5 Blue Dollars left because 7 - 2 = 5. Steve wanted to buy something else with what he had leftover. He thought he could buy a pair of green socks, but they were worth 6 Blue Dollars and he was 1 Blue Dollar short. He buys himself a green hat which was worth 3 Blue Dollars and he had 2 Blue Dollars left because 5 - 3 = 2. After purchasing the new crayon and green hat, Steve gets going but finds the 3rd clue on 1 of 2 (the other was sliced in 1/2) lemons. Steve draws the 3rd clue with his new crayon into his notebook. After realizing that they have all 3 clues, Steve skidoos back home with Blue and tries to put all 3 clues together. The clues were ice cubes, a cup and lemons. Steve thought maybe Blue could have a lemon wear the cup as a hat and slip around on the ice cubes. That was a wrong answer. Suddenly, the viewers had answer which was lemonade, because lemonade is made from lemons and ice cubes which is poured into a cup. After figuring out Blue's Clues, Steve & Blue head outside figuring out where they can find some lemonade. Sure enough, they see Shovel and Pail at the toll booth. They had lemonade to sell. Steve had to pay Cash Register 1 Blue Dollar for the lemonade. He did so and Blue got to enjoy it. Steve declares that he has 1 Blue Dollar left in his savings. Steve goes back inside and sings the So Long Song and the episode ends.
