The widely-known <em>5 Practices for Orchestrating Mathematical Discussions <\/em>were based in part on TTP<em>.<\/em> Teachers study the curriculum, anticipate student thinking, and select and sequence the student presentations that allow the class to build the new mathematics. Classroom routines for presentation and discussion of student work, board organization, and reflective mathematics journals work together to allow students to do the mathematical heavy lifting. To learn more about journals, board work, and discussion in TTP, as well as see other TTP resources and examples of TTP in action, click on the respective tabs near the top of this page.<\/p>\n<p><span style=\"font-weight: 400;\">The &#8220;Get Started&#8221; tab provides a full professional learning agenda and resources to build TTP within your school, network, or classroom.<\/span><\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_3,1_3,1_3&#8243; use_custom_gutter=&#8221;on&#8221; make_equal=&#8221;on&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; width=&#8221;86%&#8221; max_width=&#8221;1100px&#8221; module_alignment=&#8221;center&#8221; custom_padding=&#8221;||0px||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_3&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#FFFFFF&#8221; border_radii=&#8221;on|15px|15px|15px|15px&#8221; box_shadow_style=&#8221;preset1&#8243; box_shadow_vertical=&#8221;5px&#8221; box_shadow_blur=&#8221;12px&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_code _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<a class=\"et_pb_so_resource  et_pb_so_resource_0 custom_target \" href=\"https:\/\/lessonresearch.net\/wp-content\/uploads\/2020\/07\/Additional-Reading.pdf\" target=\"_blank\"><div class=\"resource-inner\">\n        <h5 class=\"resource-title\">Additional Readings<\/h5>\n    <span class=\"resource-link document_link\">Download<\/span><img decoding=\"async\" src=\"https:\/\/lessonresearch.net\/wp-content\/uploads\/2018\/01\/pdf.jpg\" class=\"download-icon\"><\/div><\/a>[\/et_pb_code][\/et_pb_column][et_pb_column type=&#8221;1_3&#8243; disabled_on=&#8221;on|on|on&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#FFFFFF&#8221; border_radii=&#8221;on|15px|15px|15px|15px&#8221; box_shadow_style=&#8221;preset1&#8243; box_shadow_vertical=&#8221;5px&#8221; box_shadow_blur=&#8221;12px&#8221; disabled=&#8221;on&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; header_5_font=&#8221;GalanoGrotesqueAltMedium|500|||||||&#8221; header_5_font_size=&#8221;20px&#8221; header_5_line_height=&#8221;28px&#8221; background_enable_color=&#8221;off&#8221; custom_padding=&#8221;30px|34px|30px|34px|true|true&#8221; link_option_url=&#8221;https:\/\/drive.google.com\/file\/d\/0Byrs5dgaCevjVmpyX3hoOUI2TkE\/view&#8221; border_radii=&#8221;on|15px|15px|15px|15px&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<div class=\"resource-inner\">\n<h5 class=\"resource-title\">How Many Seats?
