Exploring Place Value: Ones and Tens

In this video tutorial, Teacher Angel introduces the concept of place value, focusing on visualizing and understanding the place value of one to two-digit numbers. The session begins with a review of counting numbers up to 50 and finding missing numbers. The teacher then uses popsicle sticks to demonstrate how numbers can be grouped into tens and ones, illustrating the concept of place value. An exercise follows, where students practice identifying the place value of numbers. The session concludes with a brief preview of the next topic, which will cover problem-solving exercises related to place value.
