What's hiding under the cups? Today we hide letter cards under upturned cups, and your little one lifts each one, says the letter and hunts for every E. It's a guessing game, a memory game and a letter game all in one.

Each page shows a pair of dinosaurs that are opposites: loud and quiet, big and small, fierce and gentle, fast and slow. The rhyming text is short and bouncy, and the ending brings all the dinosaurs together.

E is our fifth letter! It makes a short /e/ sound at the start of words like egg, elephant and elf. Sometimes E says its own name, too, like in "eat." For now, we're listening for /e/.

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.
