Memory verses: I love the program put out by John Piper's ministry. It's part of his "Children Desiring God" series and costs as low as $5 or high as $25 depending which "pack" or "kit" you buy.
Bible curriculum for that age, I like a couple things. There's Christian Liberty Press Bible's bible workbooks. It's a nice, thorough curriculum & it's pretty cheap at $8 a level, K-6.
Love Sinclaire Ferguson's two volume Big Book series for that age. "Big Book of Questions and Answers" and "Big Book of Questions and Answers About Jesus" are both non-consumable and include memory work, scripture passages to read, discussion, and activity, $10 a book. He wrote answers to common questions children ask about God. They're enjoyable and simple to use; love the "Big Books"!
Another series I've heard good things about but haven't used myself are the classic children's devotionals for 1st-6th grade "Suffer Little Children/Show Me Thy Ways"
