TLF ID L1086

Help a frog to jump along a number line. Estimate the finishing point on a number line, after adding or subtracting multiples of decimal fractions or whole numbers to a starting number. For example, 1.72 + (11 x 0.07) = 2.49. 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.
