Bridging: this works well when subtracting a small number from another number. Subtract to the nearest 10 and then subtract the remaining part. For example, subtracting from 43, take away 3 to get to 40 and then the remainder.

What is the jump method in maths?

The jump strategy is a visual method in which an addition is performed by adding the tens and ones separately in jumps. A blank number line is drawn and each addition is shown using arrow jumps. Here is an example of an addition that will be performed using the jump strategy.

Why do we use the jump strategy?

The jump strategy is a way of adding or subtracting numbers by jumping over by increments of 10s or 1s on the number line. Perhaps it is obvious that the jump strategy can help you get the sum or the difference quickly. For example, see how quick you can get an answer for 43 + 22.

What does bridging mean in math?

Bridging through 10 is a mental Maths technique of adding two numbers whose total is greater than 10. Pupils count through to 10 then add the remainder as well. For instance, when given a sum such as 9 + 7, pupils can use the bridging through ten method as follows: 9 + 1 = 10 which leaves 6 remaining.

What is a bridge in math?

In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases the graph’s number of connected components. Equivalently, an edge is a bridge if and only if it is not contained in any cycle. A graph is said to be bridgeless or isthmus-free if it contains no bridges.

What does the game bridging through 10 and 20 mean?

The game is intended to show, through the use of a space shuttle’s flight path, how mathematicians “bridge” through friendly numbers like 10, 20, 50 and 100 while adding. When we talk to students about “making ten and some more” from two addends, we are “bridging” through ten.
