Math Clip Art--Counting Examples--Tens Model: 90

Topic

Numbers

Description

This math clip art image continues the Tens Model series, showing a 10x10 grid with nine complete columns filled, representing 90. Each column is a 10 row by 1 column array, visually demonstrating how 90 is composed of nine groups of 10.

As part of the progressive series of number modeling images for multiples of 10, this visual aid helps students build upon their understanding of smaller numbers and extend their counting skills to quantities approaching 100. It plays a crucial role in developing number sense and preparing students for more complex mathematical concepts, such as rounding to the nearest ten and understanding the base-10 system.

Using math clip art like this is essential in mathematics education, particularly for teaching number concepts and place value. This visual model helps students understand the abstract idea of "ninety" by providing a concrete representation. Seeing nine full 10x1 arrays filled reinforces the concept of grouping by tens and introduces the idea of 9 tens making 90, just short of a complete hundred.

Teacher's Script: "Let's look at our grid now. We've filled in nine whole columns. Each column has 10 squares. Let's count by tens -- 10, 20, 30, 40, 50, 60, 70, 80, 90. This represents the number 90 in our Tens Model. How many tens do we have? That's right, 9 tens! And 9 tens make 90. We're so close to filling our entire grid! How many more squares do we need to fill to reach 100?"
