Your class collects supplies and wants a fast estimate. If you round to the nearest ten, what is the estimated total for $156$ , $42$ , and $89$ ?

$280$
$290$ (correct answer)
$300$
$287$

Explanation: This question tests ISEE Lower Level skills in using place value to estimate sums and differences. Estimation involves rounding numbers to their most significant place value to simplify calculations. In this scenario, 156, 42, 89 round to 160, 40, 90, sum 290. The correct answer is choice B, $290, because 160+40+90=290. Choice C, $300, is incorrect as it overestimates. To teach this skill, encourage students to practice rounding and estimating with everyday examples, such as shopping or travel plans, and to double-check their estimations by quickly reviewing their rounding decisions.
