Season overview
The season will continue the show's two-year initiative “My World is Green & Growing,” an initiative embracing a robust science and mathematics curriculum. For season 41, Sesame Street will address the processes of scientific investigation, with 13 shows focused on this topic. One of the main curricular goals is to encourage children to think scientifically and to model the scientific process.

The 4th Annual aniBOOM Awards, aniBOOM Awards 4 Sesame Street, decided a new educational, animated short that will debut this season, a stop-motion remake of "Pinball Number Count.

Episodes
In one episode, Hooper's Store celebrates "Twins Day." Abby and Zoe want to become twins so they can participate in the festivities. The episode, written by Annie Evans and directed by Joey Mazzarino, discusses the differences between fraternal and identical twins, and that everyone is different in their own way, even if they look the same. The episode features Abby, Zoe, Telly, the Count, Chris and Christopher Lawrence Knowings' real twin sister, Christy.

Elmo and Telly go on "Noise Patrol" in an episode written by Annie Evans entitled "Don’t Wake the Baby." Leela babysits her niece and Telly and Elmo try to keep the street quiet.

Another episode, directed by Ken Diego, features Telly Monster and the Itsy Bitsy Spider (played by Leslie Carrara).

Big Bird and Elmo sleep over Maria and Luis's apartment.

In another episode, Oscar the Grouch starts a new company, Dirtballs, which spreads dirt all around Sesame Street. He employs two assistants, Hiram and Burt. Luis is happy to get some new dirt -- he'd run out of soil for his garden. Leela makes a game out of finding "hidden treasures" inside the dirt, including an acorn, a dog bone that Barkley buried in the park, and a worm. Oscar is aggravated that his dirt is helping people instead of messing up the street, so he ends the dirtball business.

In another episode, movie star Ryan Reynolds guest stars as capital letter A, and invites Elmo, Abby Cadabby and Telly Monster to join "the A Team," which tries to solve all of life's problems using A words. He tries to distract two little pigs from Oscar's trash can by showing them Alan in an afro getting chased by an alligator with an attitude, then an ape (Matt Vogel) dressed as an angel, singing about acorns. When they all fail, they decide to use another "A" word: ask. When that succeeds, Oscar thinks he's finally off the hook, but then they sing their "A Team" anthem, to Oscar's dismay. They also help Baby Bear get Curly Bear to take a nap.

Another episode involves Big Bird explaining to Snuffy how birds bathe: dust bathing. They fluff their wings and let the dust from the ground soak through their feathers. However, Big Bird can't understand why Snuffy keeps sneezing...

Another episode involves a rainy day on Sesame Street. Oscar catches rain in a bucket and Big Bird and Rosita walk to Hooper's together, sharing an umbrella. Rosita holds the umbrella, and Big Bird can't figure out why he's still getting wet. Elmo splashes in the puddles.

One developed insert involves Telly Monster and Oscar the Grouch demonstrating the letter N - with Oscar using negative and nasty words and Telly using nice ones.

An episode directed by Kevin Clash will feature Abby learning about math from The Count while looking for her missing wand.
