1) The lesson plan reviews vocabulary about bugs, numbers up to 100, and the grammatical structure "there is/are" and "how many x are there?". 2) The warm up activity involves completing a crossword with bug vocabulary. Then, students read numbers aloud from their textbook and ask each other "how many x are there?" questions about bugs. 3) New numbers are introduced through bingo, where students listen to numbers called out and check them off on their bingo cards. Homework is assigned from the textbook.
