Use this animal camouflage themed activity to target learning at the concrete, representational, and/ or abstract level. Direct your instruction to one level or overlap two levels. Make learning accessible for all your students!

A Concrete Level Task for 10 and 100 Less and More

To start, model with base ten blocks and a place value mat. As always, provide multiple opportunities for your students to practice.

• Choose a number card.
• Build the number on the place value mat using base ten blocks.
• Focus on each skill individually (10 less, 10 more, 100 less, or 100 more) or all four skills combined.
• Add or remove a ten rod or a hundred flat to model how the number changes each time. If you are lucky enough to have more than one color, use a different color of base ten blocks for adding tens or hundreds.
• When completing all the skills for a given number, combine this activity with the drawing sheet and/ or the recording sheet to bridge between levels of instruction.

A Representational Level Task

Remember to model and provide many practice opportunities at this level, too!

• Substitute the drawing sheet for the mat and base ten blocks.
• Draw hundreds, tens, and ones with squares, lines, and dots.
• For ten less, draw the start number. Cross out a ten.
• For ten more, draw the start number. Then add ten more.
• Complete in a similar manner for 100 less and more.
• Use a different color crayon or marker to cross out and add.
• To make connections between levels, combine this activity with the recording sheet.

An Abstract Level Task for  10 and 100 Less and More

Simply pick a number card. Write that number on the recording sheet in the gray column. Then, write the numbers that are 10 and 100 less and more in the corresponding columns. Repeat with a new number card.

How to Prepare 10 and 100 Less and More

• Decide how you will use this activity (concrete, representational, and/ or abstract).
• Determine the materials you will need.
• Choose the color or black/ gray/ white version.
• Print and laminate the 3 digit number cards and hundreds, tens, and, ones place value mat; one mat for each student or each small group to share. Use cardstock for durability.
• Cut the number cards.
• Make copies of the drawing sheet. Use these with dry erase pockets along with dry erase crayons or markers to save paper.
