A number analogy uses the same shape as a word analogy, with numbers. One pair shows the rule, such as adding, multiplying, or changing by a fixed amount. You choose the number that completes the next pair. QuizPrint offers this quantitative item from Grade 1 through Grade 8. Early grades keep the arithmetic small. The sample is Grade 3. Number series are a list, not a pair, and they have their own page. QuizPrint is not affiliated with Riverside Insights, and these worksheets are not official CogAT questions.
