3. Misconception concerning decimals

What could cause this type of misconception concerning DECIMALS?

0.21 = 0.0021 ??

It is called "whole-number thinking". Some students think that the digits on the right side of the decimal point make another whole number. Such students have not fully made the connection between decimals and fractions.

Whole-number thinkers are likely to say that the number after 4.9 (4 wholes and 9 parts) is 4.10 (4 wholes and 10 parts).

Sometimes students with this type of misconception believe 0.021 is larger than 0.21 just because it is longer. Other students look more carefully at the decimal part as a whole number, so that they will think that 0.21 and 0.0021 are equal, because the two whole numbers 21 and 0021 are equal.

To challenge this misconception, use decimals of different lengths.

4. Number Bonds game

A new game/activity at Math Mammoth Practice: Number Bonds. It is meant for kindergarten and 1st grade.

The child can either work with pictures (jewels) or with numbers. In each exercise, the number at the top is the sum. The child will choose from several possible numbers of jewels, or just numbers, to fill in the missing quantity (or number).
