Bundle It! Place Value to 99

About This Resource

A complete Grade 1 math pack on place value for numbers to 99. Children bundle ten ones into one ten, read base-ten blocks, say how many tens and ones are in a number, write numbers in expanded form (47 = 40 + 7) and find the value of each digit. Includes slides with worked examples, a lesson plan, worksheet, quiz, homework, flashcards, a rubric and answer keys.

Overview

Children learn that ten ones can be bundled together to make one ten, and that every two-digit number is made of tens and ones. In 34, the 3 means three tens (30) and the 4 means four ones. Children bundle straws or sticks into tens, read base-ten block pictures, write how many tens and ones are in a number, write numbers in expanded form and find the value of an underlined digit. The lesson ends with children drawing numbers with tens and ones of their own.

Learning Objectives

Understand that ten ones make one ten.
Say how many tens and ones are in a two-digit number.
Write two-digit numbers in expanded form and find the value of each digit.

How to Use This Resource

Start with the slides: count 23 straws one by one, then bundle them into tens and count again.
Teach tens and ones with the worked examples, then do worksheet activities 1 and 2 together.
Children complete activities 3 to 6, then use the quiz and take home the homework page.

Classroom Activity Ideas

Bundle it: children count straws or craft sticks, bundle groups of ten with rubber bands and say the number in tens and ones.
Show me: call out a number; children show it with base-ten blocks or drawings of sticks and dots.
Number detective: children find two-digit numbers in the classroom and say how many tens and ones they have.

Differentiation

Support: use real straws or blocks for every question and keep numbers below 50. Challenge: children find different ways to make a number (34 is 3 tens and 4 ones, or 2 tens and 14 ones).

Assessment

Use the worksheet and quiz to check reading and writing tens and ones. Use the rubric while children build numbers with straws or blocks.

Teacher Tips

Children often read 34 as three and four. Keep saying both forms together: 34 is 3 tens and 4 ones, which is 30 and 4. Numbers with zero ones (40) and teen numbers (14 = 1 ten and 4 ones) need extra practice.
