Counting Groups of Ten and Ones to 50

MatholiaChannel

This educational video provides a clear, step-by-step demonstration of how to count collections of objects up to 50 using place value strategies. Instead of counting by ones, the video models the more efficient method of counting groups of ten first (skip counting), followed by counting on the remaining single units. This visual approach reinforces the concept of base-ten number systems. The video is structured around six distinct examples using common items like marbles, cubes, cookies, and strawberries. For each example, objects are arranged in clear rows of ten to facilitate visual grouping. The narrator counts the tens ("10, 20..."), adds the ones ("and 1 is 21"), and then explicitly demonstrates how to write both the numerical digit and the number word (e.g., "twenty-one") in cursive script. For educators, this resource is an excellent tool for introducing or reinforcing place value, two-digit number formation, and connecting numerals to number words. It effectively bridges the gap between concrete visual representations (objects) and abstract numerical symbols, making it ideal for early primary math lessons on counting, cardinality, and number sense.
