Learning Number Bonds of 5 with Cubes

MatholiaChannel

This instructional video provides a clear, step-by-step demonstration of number bonds for the number 5 using concrete manipulatives. By utilizing connecting cubes in two contrasting colors (yellow and green), the video systematically explores every possible integer combination that sums to 5, starting from 5+0 and proceeding to 0+5. The visual representation of a "cube train" changing color one block at a time effectively illustrates the concept of decomposition and the relationship between parts and a whole. The video covers key mathematical themes essential for early numeracy, specifically the part-part-whole relationship and the foundational logic of addition. It subtly introduces the commutative property by showing that 2+3 and 3+2 both result in the same whole. The use of a standard number bond diagram (three connected circles) alongside the physical cubes helps bridge the gap between concrete objects and abstract mathematical notation. For educators, this video serves as an excellent model for introducing addition facts without relying initially on written equations. It is particularly useful for visual learners and can be easily replicated in the classroom using physical manipulatives. The pacing allows for interactive viewing, where students can predict the next number bond before it is revealed, making it a versatile tool for both direct instruction and guided practice in early elementary mathematics.
