# Spotting Numbers and Visual Patterns

Here a two great websites that provide lots of great pattern problems.

[this website hasn’t been functional lately – too bad!Spotting Numbersinteractive, does require Java.]

Visual Patterns – less interactive, (no Java needed).

These patterns can be used with elementary students (if you just ask number questions) through advanced algebra (if you include questions about functions).

Mathematics is often described as the study of patterns.  That is exactly what Spotting Numbers and Visual Patterns do.

The interplay of geometry and numbers and algebraic thinking in these questions puts the learner squaring at the core of mathematical reasoning.  Quite frankly, it doesn’t get much better than this!  (OK, my opinion.)

## Questions to Ask

Here are some questions.  As a general rule, For Elementary: a-b; Middle School: a-d; Algebra: a-e

a. How many *** are in next figure?
b. How many *** are in next figure after that?
c. How many *** are in pattern n = 10?
d. How many *** are in pattern n = 43?
e. Generalize: How many *** are in pattern n?
