It's Letter E day, so snack time is all about the /e/ sound, like egg. Your little one hears the sound again and again, builds a big E on the plate and then eats it. Bonus: eggs are a dinosaur-week favorite, since baby dinosaurs hatched from eggs too.

We've counted up to 4. Today we add one more and get 5. Five is the easiest number to carry around, because it's right on your hand: five fingers on each hand and five toes on each foot.

If you're starting dinosaur week with a two-year-old, start here. Dinosaurs, Dinosaurs by Byron Barton is a simple, bold introduction to all kinds of dinosaurs, and it's one of the first dinosaur books many kids fall in love with.

Welcome to dinosaur week! We're kicking it off with a snack that looks like a tiny dig site. Your little one layers creamy pudding and crumbly cookie "dirt" in a cup, then hides a dinosaur on top. Dinosaur Dirt Cups are messy, a little silly and a big hit at our table.

Today your little one becomes a paleontologist, a scientist who digs up fossils. We bury five toy dinosaurs in a bin of sand or rice, and they dig, dust and count until every one is found.

A full week of dinosaur activities for ages 2 to 4: dino snacks, a fossil dig, favorite dinosaur books, talk-about-it questions and free printables, all in one place.

Everything we use for Letter E in one place: a snack plate, a quick talk, a letter game, a book and a free tracing page. For parents and caregivers of children ages 2 to 4.

Everything we use for the number 5 in one place: a quick talk, a counting game, a snack, a book and a free tracing page. For parents and caregivers of children ages 2 to 4.

We're ending senses week with a taste adventure. Your little one tries sweet fruits and sour fruits side by side, makes their best sour face, and decides which side of the plate they like best.

The land is hot and dry. One by one, the animals notice clues that rain is on its way. They smell it, see the lightning, hear the thunder and feel the first drops. When the rain finally comes, everything turns green and the animals enjoy it, until the land slowly dries again.

Is there a better sound than popping bubble wrap? Today it becomes a counting game. You write numbers on a strip of bubble wrap, and your little one pops that many bubbles, counting (and listening) as they go.

Our noses can take us on a trip! People around the world use spices and herbs that smell wonderful: cinnamon, ginger, cumin, basil, vanilla and many more. The smells in your kitchen might remind you of family, holidays and favorite meals.

We've spent the week trying each sense. Today we put them together. Before we even see something, our senses can give us clues: we smell cookies baking, we hear the bath running, we feel rain on our skin. Each clue helps us figure out what's happening.

Soft, bumpy, scratchy, smooth. Today your little one makes a collage they can feel with their fingers. They choose materials from around the house, glue them down, then touch each one and name how it feels.

Today snack time turns into a listening experiment. Your little one tastes a few foods, listens closely to each bite, and sorts them into crunchy, soft or somewhere in between. It's the loudest science test you'll ever do.

Animal after animal makes its own sound: cats purr, lions roar, owls hoot, bees buzz and dogs growl. On each page, the children in the book listen. At the end they share what makes people special: we speak!

All you need is a cup of water and a brush. Today your little one paints letters on a fence, wall or path with plain water, then watches them slowly disappear as they dry. It's magic, it's mess-free, and they'll want to do it again and again.

The book takes each sense in turn: sight, hearing, smell, taste and touch. For each one, it pairs clear photos of everyday things with simple words that describe them, like cold, crunchy, colorful, soft and loud. It encourages kids to notice what's around them and find the words to talk about it.

Today we're learning D. For toddlers the goal isn't writing it. It's hearing the /d/ sound at the start of words like dog, duck and dad, and connecting it to the shape of D: a straight line and a big curve.

It's Letter D day, so snack time is all about the /d/ sound, like dip. Your little one hears the sound again and again, dunks, dips and crunches, and builds a big D out of snacks before eating it.
