2015-2016 Curriculum Blueprint
Grade: 5
Course: Mathematics
Topic 2 – Add and Subtract Decimals to Hundredths
Flexible Time
Line
8 days
Topic Overview
Topic 2 focuses on deep understanding of decimal addition and subtraction to the hundredths place. The students will use visual models and strategies,
including the standard algorithms.
Vertical Progression
4th Grade: The students will be able to perform whole-numbers operations, multiply fractions, and write fractions in decimal notation.
6th Grade: The students will be able to evaluate expression including decimals and exponents and fluently complete operations with both whole-numbers and
decimals.
Learning Goal
Essential Question
Students will be able to estimate decimal sums and differences, as well as add and How can sums and differences of decimals be estimated?
subtract decimals through the use of various strategies.
