Comparing and Ordering Numbers to 20

MatholiaChannel

This animated math video provides a clear, step-by-step tutorial on comparing and arranging whole numbers up to 20. It begins by grounding the concept in concrete visual representations, using characters who hold boards with specific quantities of stickers arranged in ten-frames and singles. This visual aid helps students connect the abstract numeral to actual quantity. The video then transitions to ordering abstract numbers written on cards, demonstrating both ascending (smallest to greatest) and descending (greatest to smallest) order. The content focuses on key number sense skills including identifying quantity, using comparison vocabulary like 'smaller' and 'greater,' and employing systematic strategies for ordering sets of three to five numbers. It explicitly models the cognitive process of elimination—identifying the extreme value (smallest or greatest) first, removing it from the set, and then comparing the remaining numbers. For educators, this video serves as an excellent instructional model for early primary math. It scaffolds learning by moving from pictorial to abstract representations and introduces the practical 'cross-out' strategy for organizing multiple numbers. It is particularly useful for introducing the concept of sequencing non-consecutive numbers and reinforcing place value concepts through the visual grouping of tens and ones.
