A quick check for kindergarteners to identify if a quantity increases or decreases in a simple story context.
A high-energy matching activity where students pair neon digital clock displays with standard digital time cards. Focuses on reinforcing identification of hours and half-hours through kinesthetic play.
Synthesizes all skills to represent any two-digit number through drawing, expanded form, and word problems.
Practice with multiples of 10, connecting counting by tens to place value charts and number names.
Practice with numbers 11-19, representing them as '1 ten and some ones' using varied phrasing and visual models.
Focuses on the core concept of bundling 10 ones to make 1 ten. Includes high-repetition practice circling groups of ten and counting leftovers.
Students delve into the structure of the number 12, exploring it as one ten and two ones, and practice simple addition strategies to reach the sum of 12.
A hands-on lesson focused on counting quantities up to 13 and using the terms 'more' and 'less' to compare groups of objects. Students will practice visual estimation, precise counting, and basic mathematical comparison symbols.
A lesson focused on counting mixed sets of circles and triangles up to 15, helping students develop one-to-one correspondence and number writing skills.
A comprehensive review of normal distribution calculations, including z-score conversion and probability determination for various real-world scenarios. Students will calculate left-tail, right-tail, and interval probabilities and evaluate the rarity of events.
A lesson focused on mastering double-digit multiplication through problems that require advanced regrouping in both partial product steps. Students use a structured grid to organize their work and ensure place value alignment.
A comprehensive lesson focusing on constructing linear and exponential models and analyzing function transformations. Students will compare function families and evaluate how parameters shift and stretch graphs.
A lesson on understanding and graphing inequalities with negative numbers using the real-world context of temperature and thermometers. Students will master the 'flip the sign' rule when multiplying or dividing by negatives.
