# Hopper: whole numbers

TLF ID L1084

Help a frog to jump along a number line. Estimate the finishing point on a number line, after adding or subtracting multiples of whole numbers to a starting number. For example, 255+(10 x 4) = 295. Explore the patterns made on a counting grid and number line. Identify counting rules that match the pattern of 'landing spots' on a counting grid. This learning object is one in a series of seven objects.

#### Educational details
